49 ;; This package provides printing of Emacs buffers on PostScript printers; the
50 ;; buffer's bold and italic text attributes are preserved in the printer
51 ;; output. ps-print is intended for use with Emacs or XEmacs, together with a
52 ;; fontifying package such as font-lock or hilit.
54 ;; ps-print uses the same face attributes defined through font-lock or hilit to
55 ;; print a PostScript file, but some faces are better seeing on the screen than
56 ;; on paper, specially when you have a black/white PostScript printer.
58 ;; ps-print allows a remap of face to another one that it is better to print,
59 ;; for example, the face font-lock-comment-face (if you are using font-lock)
60 ;; could have bold or italic attribute when printing, besides foreground color.
61 ;; This remap improves printing look (see How Ps-Print Maps Faces).
67 ;; ps-print provides eight commands for generating PostScript images of Emacs
71 ;; ps-print-buffer-with-faces
73 ;; ps-print-region-with-faces
75 ;; ps-spool-buffer-with-faces
77 ;; ps-spool-region-with-faces
79 ;; These commands all perform essentially the same function: they generate
80 ;; PostScript images suitable for printing on a PostScript printer or
81 ;; displaying with GhostScript. These commands are collectively referred to as
82 ;; "ps-print- commands".
84 ;; The word "print" or "spool" in the command name determines when the
85 ;; PostScript image is sent to the printer:
87 ;; print - The PostScript image is immediately sent to the printer;
89 ;; spool - The PostScript image is saved temporarily in an Emacs
90 ;; buffer. Many images may be spooled locally before
91 ;; printing them. To send the spooled images to the
92 ;; printer, use the command `ps-despool'.
94 ;; The spooling mechanism was designed for printing lots of small files (mail
95 ;; messages or netnews articles) to save paper that would otherwise be wasted
96 ;; on banner pages, and to make it easier to find your output at the printer
97 ;; (it's easier to pick up one 50-page printout than to find 50 single-page
100 ;; ps-print has a hook in the `kill-emacs-hook' so that you won't accidentally
101 ;; quit from Emacs while you have unprinted PostScript waiting in the spool
102 ;; buffer. If you do attempt to exit with spooled PostScript, you'll be asked
103 ;; if you want to print it, and if you decline, you'll be asked to confirm the
104 ;; exit; this is modeled on the confirmation that Emacs uses for modified
107 ;; The word "buffer" or "region" in the command name determines how much of the
108 ;; buffer is printed:
110 ;; buffer - Print the entire buffer.
112 ;; region - Print just the current region.
114 ;; The -with-faces suffix on the command name means that the command will
115 ;; include font, color, and underline information in the PostScript image, so
116 ;; the printed image can look as pretty as the buffer. The ps-print- commands
117 ;; without the -with-faces suffix don't include font, color, or underline
118 ;; information; images printed with these commands aren't as pretty, but are
119 ;; faster to generate.
121 ;; Two ps-print- command examples:
123 ;; ps-print-buffer - print the entire buffer, without font,
124 ;; color, or underline information, and
125 ;; send it immediately to the printer.
127 ;; ps-spool-region-with-faces - print just the current region; include
128 ;; font, color, and underline information,
129 ;; and spool the image in Emacs to send to
130 ;; the printer later.
136 ;; To print your buffer, type
138 ;; M-x ps-print-buffer
140 ;; or substitute one of the other seven ps-print- commands. The command will
141 ;; generate the PostScript image and print or spool it as specified. By giving
142 ;; the command a prefix argument
144 ;; C-u M-x ps-print-buffer
146 ;; it will save the PostScript image to a file instead of sending it to the
147 ;; printer; you will be prompted for the name of the file to save the image to.
148 ;; The prefix argument is ignored by the commands that spool their images, but
149 ;; you may save the spooled images to a file by giving a prefix argument to
152 ;; C-u M-x ps-despool
154 ;; When invoked this way, `ps-despool' will prompt you for the name of the file
157 ;; Any of the `ps-print-' commands can be bound to keys; I recommend binding
158 ;; `ps-spool-buffer-with-faces', `ps-spool-region-with-faces', and
159 ;; `ps-despool'. Here are the bindings I use on my Sun 4 keyboard:
161 ;; (global-set-key 'f22 'ps-spool-buffer-with-faces) ;f22 is prsc
162 ;; (global-set-key '(shift f22) 'ps-spool-region-with-faces)
163 ;; (global-set-key '(control f22) 'ps-despool)
166 ;; The Printer Interface
167 ;; ---------------------
169 ;; The variables `ps-lpr-command' and `ps-lpr-switches' determine what command
170 ;; is used to send the PostScript images to the printer, and what arguments to
171 ;; give the command. These are analogous to `lpr-command' and `lpr-switches'.
173 ;; Make sure that they contain appropriate values for your system;
174 ;; see the usage notes below and the documentation of these variables.
176 ;; The variable `ps-printer-name' determines the name of a local printer for
177 ;; printing PostScript files.
179 ;; The variable `ps-printer-name-option' determines the option used by some
180 ;; utilities to indicate the printer name, it's used only when
181 ;; `ps-printer-name' is a non-empty string. If you're using lpr utility to
182 ;; print, for example, `ps-printer-name-option' should be set to "-P".
184 ;; NOTE: `ps-lpr-command' and `ps-lpr-switches' take their initial values from
185 ;; the variables `lpr-command' and `lpr-switches'. If you have
186 ;; `lpr-command' set to invoke a pretty-printer such as `enscript', then
187 ;; ps-print won't work properly. `ps-lpr-command' must name a program
188 ;; that does not format the files it prints.
189 ;; `ps-printer-name' takes its initial value from the variable
190 ;; `printer-name'. `ps-printer-name-option' tries to guess which system
191 ;; Emacs is running and takes its initial value in accordance with this
194 ;; The variable `ps-print-region-function' specifies a function to print the
195 ;; region on a PostScript printer.
196 ;; See definition of `call-process-region' for calling conventions. The fourth
197 ;; and the sixth arguments are both nil.
199 ;; The variable `ps-manual-feed' indicates if the printer will manually feed
200 ;; paper. If it's nil, automatic feeding takes place. If it's non-nil, manual
201 ;; feeding takes place. The default is nil (automatic feeding).
203 ;; The variable `ps-end-with-control-d' specifies whether C-d (\x04) should be
204 ;; inserted at end of PostScript generated. Non-nil means do so. The default
205 ;; is nil (don't insert).
207 ;; If you're using Emacs for Windows 95/98/NT or MS-DOS, don't forget to
208 ;; customize the following variables: `ps-printer-name',
209 ;; `ps-printer-name-option', `ps-lpr-command', `ps-lpr-switches' and
210 ;; `ps-spool-config'. See these variables documentation in the code or by
211 ;; typing, for example, C-h v ps-printer-name RET.
217 ;; All dimensions are floats in PostScript points.
218 ;; 1 inch == 2.54 cm == 72 points
219 ;; 1 cm == (/ 1 2.54) inch == (/ 72 2.54) points
221 ;; The variable `ps-paper-type' determines the size of paper ps-print formats
222 ;; for; it should contain one of the symbols: `a4' `a3' `letter' `legal'
223 ;; `letter-small' `tabloid' `ledger' `statement' `executive' `a4small' `b4'
226 ;; If variable `ps-warn-paper-type' is nil, it's *not* given an error if
227 ;; PostScript printer doesn't have a paper with the size indicated by
228 ;; `ps-paper-type', instead it uses the default paper size. If variable
229 ;; `ps-warn-paper-type' is non-nil, it's given an error if PostScript printer
230 ;; doesn't have a paper with the size indicated by `ps-paper-type'. It's used
231 ;; when `ps-spool-config' is set to `setpagedevice' (see section Duplex
232 ;; Printers). The default value is non-nil (it gives an error).
234 ;; The variable `ps-landscape-mode' determines the orientation of the printing
235 ;; on the page: nil means `portrait' mode, non-nil means `landscape' mode.
236 ;; There is no oblique mode yet, though this is easy to do in ps.
238 ;; In landscape mode, the text is NOT scaled: you may print 70 lines in
239 ;; portrait mode and only 50 lines in landscape mode. The margins represent
240 ;; margins in the printed paper: the top margin is the margin between the top
241 ;; of the page and the printed header, whatever the orientation is.
243 ;; The variable `ps-number-of-columns' determines the number of columns both in
244 ;; landscape and portrait mode.
246 ;; - (the standard) one column portrait mode.
247 ;; - (my favorite) two columns landscape mode (which spares trees).
249 ;; - one column landscape mode for files with very long lines.
250 ;; - multi-column portrait or landscape mode.
252 ;; The variable `ps-print-upside-down' determines other orientation for
253 ;; printing page: nil means `normal' printing, non-nil means `upside-down'
254 ;; printing (that is, the page is rotated by 180 grades). The default value is
255 ;; nil (`normal' printing).
257 ;; The `upside-down' orientation can be used in portrait or landscape mode.
259 ;; The variable `ps-selected-pages' specifies which pages to print. If it's
260 ;; nil, all pages are printed. If it's a list, the list element may be an
261 ;; integer or a cons cell (FROM . TO) designating FROM page to TO page; any
262 ;; invalid element is ignored, that is, an integer lesser than one or if FROM
263 ;; is greater than TO. Otherwise, it's treated as nil. The default value is
264 ;; nil (print all pages). After ps-print processing `ps-selected-pages' is set
265 ;; to nil. But the latest `ps-selected-pages' is saved in
266 ;; `ps-last-selected-pages' (see it for documentation). So you can restore the
267 ;; latest selected pages by using `ps-last-selected-pages' or by calling
268 ;; `ps-restore-selected-pages' command (see it for documentation).
270 ;; The variable `ps-even-or-odd-pages' specifies if it prints even/odd pages.
274 ;; nil print all pages.
276 ;; even-page print only even pages.
278 ;; odd-page print only odd pages.
280 ;; even-sheet print only even sheets.
282 ;; odd-sheet print only odd sheets.
284 ;; Any other value is treated as nil. The default value is nil.
286 ;; See `ps-even-or-odd-pages' for more detailed documentation.
292 ;; The horizontal layout is determined by the variables
293 ;; `ps-left-margin' `ps-inter-column' `ps-right-margin'
296 ;; ------------------------------------------
298 ;; | lm | text | ic | text | ic | text | rm |
300 ;; ------------------------------------------
302 ;; If `ps-number-of-columns' is 1, `ps-inter-column' is not relevant.
303 ;; Usually, lm = rm > 0 and ic = lm
304 ;; If (ic < 0), the text of adjacent columns can overlap.
310 ;; The vertical layout is determined by the variables
311 ;; `ps-bottom-margin' `ps-top-margin' `ps-header-offset' `ps-footer-offset'
314 ;; |--------| |--------| |--------| |--------|
315 ;; | tm | | tm | | tm | | tm |

332 ;; If `ps-print-header' is nil, `ps-header-offset' is not relevant.
333 ;; If `ps-print-footer' is nil, `ps-footer-offset' is not relevant.
334 ;; The margins represent margins in the printed paper:
335 ;; the top margin is the margin between the top of the page and the printed
336 ;; header, whatever the orientation is;
337 ;; the bottom margin is the margin between the bottom of the page and the
338 ;; printed footer, whatever the orientation is.
344 ;; ps-print can print headers at the top of each column or at the top of each
345 ;; page; the default headers contain the following four items: on the left, the
346 ;; name of the buffer and, if the buffer is visiting a file, the file's
347 ;; directory; on the right, the page number and date of printing. The default
348 ;; headers look something like this:
351 ;; /home/jct/emacs-lisp/ps/new 94/12/31
353 ;; When printing on duplex printers, left and right are reversed so that the
354 ;; page numbers are toward the outside (cf. `ps-spool-duplex').
356 ;; Headers are configurable:
357 ;; To turn them off completely, set `ps-print-header' to nil.
358 ;; To turn off the header's gaudy framing box,
359 ;; set `ps-print-header-frame' to nil.
361 ;; The variable `ps-header-frame-alist' specifies header frame properties
362 ;; alist. Valid frame properties are:
364 ;; fore-color Specify the foreground frame color.
365 ;; It should be a float number between 0.0 (black color)
366 ;; and 1.0 (white color), a string which is a color name,
367 ;; or a list of 3 float numbers which corresponds to the
368 ;; Red Green Blue color scale, each float number between
369 ;; 0.0 (dark color) and 1.0 (bright color).
370 ;; The default is 0 ("black").
372 ;; back-color Specify the background frame color (similar to
373 ;; fore-color). The default is 0.9 ("gray90").
375 ;; shadow-color Specify the shadow color (similar to fore-color).
376 ;; The default is 0 ("black").
378 ;; border-color Specify the border color (similar to fore-color).
379 ;; The default is 0 ("black").
381 ;; border-width Specify the border width.
382 ;; The default is 0.4.
384 ;; Any other property is ignored.
386 ;; Don't change this alist directly, instead use customization, or `ps-value',
387 ;; `ps-get', `ps-put' and `ps-del' functions (see them for documentation).
389 ;; To print only one header at the top of each page, set
390 ;; `ps-print-only-one-header' to t.
392 ;; To switch headers, set `ps-switch-header' to:
394 ;; nil Never switch headers.
396 ;; t Always switch headers.
398 ;; duplex Switch headers only when duplexing is on, that is, when
399 ;; `ps-spool-duplex' is non-nil (see Duplex Printers).
401 ;; Any other value is treated as t. The default value is `duplex'.
403 ;; The font family and size of text in the header are determined by the
404 ;; variables `ps-header-font-family', `ps-header-font-size' and
405 ;; `ps-header-title-font-size' (see below).
407 ;; The variable `ps-header-line-pad' determines the portion of a header title
408 ;; line height to insert between the header frame and the text it contains,
409 ;; both in the vertical and horizontal directions: .5 means half a line.
411 ;; Page numbers are printed in `n/m' format, indicating page n of m pages; to
412 ;; omit the total page count and just print the page number, set
413 ;; `ps-show-n-of-n' to nil.
415 ;; The amount of information in the header can be changed by changing the
416 ;; number of lines. To show less, set `ps-header-lines' to 1, and the header
417 ;; will show only the buffer name and page number. To show more, set
418 ;; `ps-header-lines' to 3, and the header will show the time of printing below
421 ;; To change the content of the headers, change the variables `ps-left-header'
422 ;; and `ps-right-header'.
423 ;; These variables are lists, specifying top-to-bottom the text to display on
424 ;; the left or right side of the header. Each element of the list should be a
425 ;; string or a symbol. Strings are inserted directly into the PostScript
426 ;; arrays, and should contain the PostScript string delimiters '(' and ')'.
428 ;; Symbols in the header format lists can either represent functions or
429 ;; variables. Functions are called, and should return a string to show in the
430 ;; header. Variables should contain strings to display in the header. In
431 ;; either case, function or variable, the PostScript string delimiters are
432 ;; added by ps-print, and should not be part of the returned value.
434 ;; Here's an example: say we want the left header to display the text
440 ;; where we have a function to return "Moe"
442 ;; (defun moe-func ()
445 ;; a variable specifying "Larry"
447 ;; (setq larry-var "Larry")
449 ;; and a literal for "Curly". Here's how `ps-left-header' should be set:
451 ;; (setq ps-left-header (list 'moe-func 'larry-var "(Curly)"))
453 ;; Note that Curly has the PostScript string delimiters inside his quotes --
454 ;; those aren't misplaced lisp delimiters!
456 ;; Without them, PostScript would attempt to call the undefined function Curly,
457 ;; which would result in a PostScript error.
459 ;; Since most printers don't report PostScript errors except by aborting the
460 ;; print job, this kind of error can be hard to track down.
462 ;; Consider yourself warned!
464 ;; ps-print also print footers. The footer variables are: `ps-print-footer',
465 ;; `ps-footer-offset', `ps-print-footer-frame', `ps-footer-font-family',
466 ;; `ps-footer-font-size', `ps-footer-line-pad', `ps-footer-lines',
467 ;; `ps-left-footer', `ps-right-footer' and `ps-footer-frame-alist'. These
468 ;; variables are similar to those one that control headers.
470 ;; The variables `ps-print-only-one-header' and `ps-switch-header' also control
471 ;; the footer (The same way that control header).
473 ;; As a footer example, if you want to have a centered page number in the
474 ;; footer but without headers, set:
476 ;; (setq ps-print-header nil
478 ;; ps-print-footer-frame nil
480 ;; ps-right-footer nil
482 ;; (list (concat "{pagenumberstring dup stringwidth pop"
483 ;; " 2 div PrintWidth 2 div exch sub 0 rmoveto}")))
486 ;; PostScript Prologue Header
487 ;; --------------------------
489 ;; It is possible to add PostScript prologue header comments besides that
490 ;; ps-print generates by setting the variable `ps-print-prologue-header'.
492 ;; `ps-print-prologue-header' may be a string or a symbol function which
493 ;; returns a string. Note that this string is inserted on PostScript prologue
494 ;; header section which is used to define some document characteristic through
495 ;; PostScript special comments, like "%%Requirements: jog\n".
497 ;; By default `ps-print-prologue-header' is nil.
499 ;; ps-print always inserts the %%Requirements: comment, so if you need to
500 ;; insert more requirements put them first in `ps-print-prologue-header' using
501 ;; the "%%+" comment. For example, if you need to set numcopies to 3 and jog
502 ;; on requirements and set %%LanguageLevel: to 2, do:
504 ;; (setq ps-print-prologue-header
505 ;; "%%+ numcopies(3) jog\n%%LanguageLevel: 2\n")
507 ;; The duplex requirement is inserted by ps-print (see section Duplex
510 ;; Do not forget to terminate the string with "\n".
512 ;; For more information about PostScript document comments, see:
513 ;; PostScript Language Reference Manual (2nd edition)
514 ;; Adobe Systems Incorporated
515 ;; Appendix G: Document Structuring Conventions -- Version 3.0
517 ;; It is also possible to add an user defined PostScript prologue code before
518 ;; all generated prologue code by setting the variable
519 ;; `ps-user-defined-prologue'.
521 ;; `ps-user-defined-prologue' may be a string or a symbol function which
522 ;; returns a string. Note that this string is inserted after `ps-adobe-tag'
523 ;; and PostScript prologue comments, and before ps-print PostScript prologue
524 ;; code section. That is, this string is inserted after error handler
525 ;; initialization and before ps-print settings.
527 ;; By default `ps-user-defined-prologue' is nil.
529 ;; It's strongly recommended only insert PostScript code and/or comments
530 ;; specific for your printing system particularities. For example, some
531 ;; special initialization that only your printing system needs.
533 ;; Do not insert code for duplex printing, n-up printing or error handler,
534 ;; ps-print handles this in a suitable way.
536 ;; For more information about PostScript, see:
537 ;; PostScript Language Reference Manual (2nd edition)
538 ;; Adobe Systems Incorporated
540 ;; As an example for `ps-user-defined-prologue' setting:
542 ;; ;; Setting for HP PostScript printer
543 ;; (setq ps-user-defined-prologue
544 ;; (concat "<</DeferredMediaSelection true /PageSize [612 792] "
545 ;; "/MediaPosition 2 /MediaType (Plain)>> setpagedevice"))
548 ;; PostScript Error Handler
549 ;; ------------------------
551 ;; ps-print instruments generated PostScript code with an error handler.
553 ;; The variable `ps-error-handler-message' specifies where the error handler
554 ;; message should be sent.
558 ;; none catch the error and *DON'T* send any message.
560 ;; paper catch the error and print on paper the error message.
561 ;; This is the default value.
563 ;; system catch the error and send back the error message to
564 ;; printing system. This is useful only if printing
565 ;; system send back an email reporting the error, or if
566 ;; there is some other alternative way to report back the
567 ;; error from the system to you.
569 ;; paper-and-system catch the error, print on paper the error message and
570 ;; send back the error message to printing system.
572 ;; Any other value is treated as `paper'.
578 ;; If you have a duplex-capable printer (one that prints both sides of the
579 ;; paper), set `ps-spool-duplex' to t.
580 ;; ps-print will insert blank pages to make sure each buffer starts on the
581 ;; correct side of the paper.
583 ;; The variable `ps-spool-config' specifies who is the responsible for setting
584 ;; duplex and page size. Valid values are:
586 ;; lpr-switches duplex and page size are configured by `ps-lpr-switches'.
587 ;; Don't forget to set `ps-lpr-switches' to select duplex
588 ;; printing for your printer.
590 ;; setpagedevice duplex and page size are configured by ps-print using the
591 ;; setpagedevice PostScript operator.
593 ;; nil duplex and page size are configured by ps-print *not* using
594 ;; the setpagedevice PostScript operator.
596 ;; Any other value is treated as nil.
598 ;; The default value is `lpr-switches'.
600 ;; WARNING: The setpagedevice PostScript operator affects ghostview utility
601 ;; when viewing file generated using landscape. Also on some
602 ;; printers, setpagedevice affects zebra stripes; on other printers,
603 ;; setpagedevice affects the left margin.
604 ;; Besides all that, if your printer does not have the paper size
605 ;; specified by setpagedevice, your printing will be aborted.
606 ;; So, if you need to use setpagedevice, set `ps-spool-config' to
607 ;; `setpagedevice', generate a test file and send it to your printer;
608 ;; if the printed file isn't ok, set `ps-spool-config' to nil.
610 ;; The variable `ps-spool-tumble' specifies how the page images on opposite
611 ;; sides of a sheet are oriented with respect to each other. If
612 ;; `ps-spool-tumble' is nil, produces output suitable for binding on the left
613 ;; or right. If `ps-spool-tumble' is non-nil, produces output suitable for
614 ;; binding at the top or bottom. It has effect only when `ps-spool-duplex' is
615 ;; non-nil. The default value is nil.
617 ;; Some printer system prints a header page and forces the first page be
618 ;; printed on header page back, when using duplex. If your printer system has
619 ;; this behavior, set variable `ps-banner-page-when-duplexing' to t.
621 ;; When `ps-banner-page-when-duplexing' is non-nil, it prints a blank page as
622 ;; the very first printed page. So, it behaves as the very first character of
623 ;; buffer (or region) is ^L (\014).
625 ;; The default for `ps-banner-page-when-duplexing' is nil (*don't* skip the
632 ;; The variable `ps-n-up-printing' specifies the number of pages per sheet of
633 ;; paper. The value specified must be between 1 and 100. The default is 1.
635 ;; NOTE: some PostScript printer may crash printing if `ps-n-up-printing' is
636 ;; set to a high value (for example, 23). If this happens, set a lower value.
638 ;; The variable `ps-n-up-margin' specifies the margin in points between the
639 ;; sheet border and the n-up printing. The default is 1 cm (or 0.3937 inches,
642 ;; If variable `ps-n-up-border-p' is non-nil a border is drawn around each
643 ;; page. The default is t.
645 ;; The variable `ps-n-up-filling' specifies how page matrix is filled on each
646 ;; sheet of paper. Following are the valid values for `ps-n-up-filling' with a
647 ;; filling example using a 3x4 page matrix:
649 ;; left-top 1 2 3 4 left-bottom 9 10 11 12
651 ;; 9 10 11 12 1 2 3 4
653 ;; right-top 4 3 2 1 right-bottom 12 11 10 9
655 ;; 12 11 10 9 4 3 2 1
657 ;; top-left 1 4 7 10 bottom-left 3 6 9 12
661 ;; top-right 10 7 4 1 bottom-right 12 9 6 3
665 ;; Any other value is treated as `left-top'.
667 ;; The default value is left-top.
670 ;; Control And 8-bit Characters
671 ;; ----------------------------
673 ;; The variable `ps-print-control-characters' specifies whether you want to see
674 ;; a printable form for control and 8-bit characters, that is, instead of
675 ;; sending, for example, a ^D (\004) to printer, it is sent the string "^D".
677 ;; Valid values for `ps-print-control-characters' are:
679 ;; 8-bit This is the value to use when you want an ASCII encoding of
680 ;; any control or non-ASCII character. Control characters are
681 ;; encoded as "^D", and non-ASCII characters have an
684 ;; control-8-bit This is the value to use when you want an ASCII encoding of
685 ;; any control character, whether it is 7 or 8-bit.
686 ;; European 8-bits accented characters are printed according
689 ;; control Only ASCII control characters have an ASCII encoding.
690 ;; European 8-bits accented characters are printed according
693 ;; nil No ASCII encoding. Any character is printed according the
696 ;; Any other value is treated as nil.
698 ;; The default is `control-8-bit'.
700 ;; Characters TAB, NEWLINE and FORMFEED are always treated by ps-print engine.
703 ;; Printing Multi-byte Buffer
704 ;; --------------------------
706 ;; See ps-mule.el for documentation.
712 ;; The variable `ps-line-number' specifies whether to number each line;
713 ;; non-nil means do so. The default is nil (don't number each line).
715 ;; The variable `ps-line-number-color' specifies the color for line number.
716 ;; See `ps-zebra-color' for documentation. The default is "black" (or 0.0, or
719 ;; The variable `ps-line-number-font' specifies the font for line number.
720 ;; The default is "Times-Italic".
722 ;; The variable `ps-line-number-font-size' specifies the font size in points
723 ;; for line number. See `ps-font-size' for documentation. The default is 6.
725 ;; The variable `ps-line-number-step' specifies the interval that line number
726 ;; is printed. For example, if `ps-line-number-step' is set to 2, the printing
739 ;; integer an integer that specifies the interval that line number is
740 ;; printed. If it's lesser than or equal to zero, it's used the
743 ;; `zebra' specifies that only the line number of the first line in a
744 ;; zebra stripe is to be printed.
746 ;; Any other value is treated as `zebra'.
747 ;; The default value is 1, so each line number is printed.
749 ;; The variable `ps-line-number-start' specifies the starting point in the
750 ;; interval given by `ps-line-number-step'. For example, if
751 ;; `ps-line-number-step' is set to 3 and `ps-line-number-start' is set to 3,
752 ;; the printing will look like:
766 ;; The values for `ps-line-number-start':
768 ;; * If `ps-line-number-step' is an integer, must be between 1 and the value
769 ;; of `ps-line-number-step' inclusive.
771 ;; * If `ps-line-number-step' is set to `zebra', must be between 1 and the
772 ;; value of `ps-zebra-stripe-height' inclusive.
774 ;; The default value is 1, so the line number of the first line of each
775 ;; interval is printed.
781 ;; Zebra stripes are a kind of background that appear "underneath" the text and
782 ;; can make the text easier to read. They look like this:
784 ;; XXXXXXXXXXXXXXXXXXXXXXXX
785 ;; XXXXXXXXXXXXXXXXXXXXXXXX
786 ;; XXXXXXXXXXXXXXXXXXXXXXXX
790 ;; XXXXXXXXXXXXXXXXXXXXXXXX
791 ;; XXXXXXXXXXXXXXXXXXXXXXXX
792 ;; XXXXXXXXXXXXXXXXXXXXXXXX
794 ;; The blocks of X's represent rectangles filled with a light gray color.
795 ;; Each rectangle extends all the way across the page.
797 ;; The height, in lines, of each rectangle is controlled by the variable
798 ;; `ps-zebra-stripe-height', which is 3 by default. The distance between
799 ;; stripes equals the height of a stripe.
801 ;; The variable `ps-zebra-stripes' controls whether to print zebra stripes.
802 ;; Non-nil means yes, nil means no. The default is nil.
804 ;; The variable `ps-zebra-color' controls the zebra stripes gray scale or RGB
805 ;; color. It should be a float number between 0.0 (black color) and 1.0 (white
806 ;; color), a string which is a color name, or a list of 3 numbers which
807 ;; corresponds to the Red Green Blue color scale.
808 ;; The default is 0.95 (or "gray95", or '(0.95 0.95 0.95)).
810 ;; The variable `ps-zebra-stripe-follow' specifies how zebra stripes continue
811 ;; on next page. Visually, valid values are (the character `+' at right of
812 ;; each column indicates that a line is printed):
814 ;; `nil' `follow' `full' `full-follow'

844 ;; See also section How Ps-Print Has A Text And/Or Image On Background.
850 ;; ps-print has the following hook variables:
853 ;; It is evaluated once before any printing process. This is the right
854 ;; place to initialize ps-print global data.
855 ;; For an example, see section Adding a New Font Family.
857 ;; `ps-print-begin-sheet-hook'
858 ;; It is evaluated on each beginning of sheet of paper.
859 ;; If `ps-n-up-printing' is equal to 1, `ps-print-begin-page-hook' is never
862 ;; `ps-print-begin-page-hook'
863 ;; It is evaluated on each beginning of page, except in the beginning of
864 ;; page that `ps-print-begin-sheet-hook' is evaluated.
866 ;; `ps-print-begin-column-hook'
867 ;; It is evaluated on each beginning of column, except in the beginning of
868 ;; column that `ps-print-begin-page-hook' is evaluated or that
869 ;; `ps-print-begin-sheet-hook' is evaluated.
875 ;; ps-print now knows rather precisely some fonts: the variable
876 ;; `ps-font-info-database' contains information for a list of font families
877 ;; (currently mainly `Courier' `Helvetica' `Times' `Palatino'
878 ;; `Helvetica-Narrow' `NewCenturySchlbk'). Each font family contains the font
879 ;; names for standard, bold, italic and bold-italic characters, a reference
880 ;; size (usually 10) and the corresponding line height, width of a space and
881 ;; average character width.
883 ;; The variable `ps-font-family' determines which font family is to be used for
884 ;; ordinary text. If its value does not correspond to a known font family, an
885 ;; error message is printed into the `*Messages*' buffer, which lists the
886 ;; currently available font families.
888 ;; The variable `ps-font-size' determines the size (in points) of the font for
889 ;; ordinary text, when generating PostScript. Its value is a float or a cons
890 ;; of floats which has the following form:
892 ;; (LANDSCAPE-SIZE . PORTRAIT-SIZE)
894 ;; Similarly, the variable `ps-header-font-family' determines which font family
895 ;; is to be used for text in the header.
897 ;; The variable `ps-header-font-size' determines the font size, in points, for
898 ;; text in the header (similar to `ps-font-size').
900 ;; The variable `ps-header-title-font-size' determines the font size, in
901 ;; points, for the top line of text in the header (similar to `ps-font-size').
903 ;; The variable `ps-line-spacing' determines the line spacing, in points, for
904 ;; ordinary text, when generating PostScript (similar to `ps-font-size'). The
905 ;; default value is 0 (zero = no line spacing).
907 ;; The variable `ps-paragraph-spacing' determines the paragraph spacing, in
908 ;; points, for ordinary text, when generating PostScript (similar to
909 ;; `ps-font-size'). The default value is 0 (zero = no paragraph spacing).
911 ;; To get all lines with some spacing set both `ps-line-spacing' and
912 ;; `ps-paragraph-spacing' variables.
914 ;; The variable `ps-paragraph-regexp' specifies the paragraph delimiter. It
915 ;; should be a regexp or nil. The default value is "[ \t]*$", that is, an
916 ;; empty line or a line containing only spaces and tabs.
918 ;; The variable `ps-begin-cut-regexp' and `ps-end-cut-regexp' specify the start
919 ;; and end of a region to cut out when printing.
921 ;; As an example, variables `ps-begin-cut-regexp' and `ps-end-cut-regexp' may
922 ;; be set to "^Local Variables:" and "^End:", respectively, in order to leave
923 ;; out some special printing instructions from the actual print. Special
924 ;; printing instructions may be appended to the end of the file just like any
925 ;; other buffer-local variables. See section "Local Variables in Files" on
926 ;; Emacs manual for more information.
928 ;; Variables `ps-begin-cut-regexp' and `ps-end-cut-regexp' control together
929 ;; what actually gets printed. Both variables may be set to nil in which case
930 ;; no cutting occurs. By default, both variables are set to nil.
933 ;; Adding a New Font Family
934 ;; ------------------------
936 ;; To use a new font family, you MUST first teach ps-print this font, i.e., add
937 ;; its information to `ps-font-info-database', otherwise ps-print cannot
938 ;; correctly place line and page breaks.
940 ;; For example, assuming `Helvetica' is unknown, you first need to do the
941 ;; following ONLY ONCE:
943 ;; - create a new buffer
944 ;; - generate the PostScript image to a file (C-u M-x ps-print-buffer)
945 ;; - open this file and find the line:
946 ;; `% 3 cm 20 cm moveto 10/Courier ReportFontInfo showpage'
947 ;; - delete the leading `%' (which is the PostScript comment character)
948 ;; - replace in this line `Courier' by the new font (say `Helvetica') to get
950 ;; `3 cm 20 cm moveto 10/Helvetica ReportFontInfo showpage'
951 ;; - send this file to the printer (or to ghostscript).
952 ;; You should read the following on the output page:
954 ;; For Helvetica 10 point, the line height is 11.56, the space width is 2.78
955 ;; and a crude estimate of average character width is 5.09243
957 ;; - Add these values to the `ps-font-info-database':
958 ;; (setq ps-font-info-database
960 ;; '((Helvetica ; the family key
961 ;; (fonts (normal . "Helvetica")
962 ;; (bold . "Helvetica-Bold")
963 ;; (italic . "Helvetica-Oblique")
964 ;; (bold-italic . "Helvetica-BoldOblique"))
966 ;; (line-height . 11.56)
967 ;; (space-width . 2.78)
968 ;; (avg-char-width . 5.09243)))
969 ;; ps-font-info-database))
970 ;; - Now you can use this font family with any size:
971 ;; (setq ps-font-family 'Helvetica)
972 ;; - if you want to use this family in another emacs session, you must put into
974 ;; (require 'ps-print)
975 ;; (setq ps-font-info-database (append ...)))
976 ;; if you don't want to load ps-print, you have to copy the whole value:
977 ;; (setq ps-font-info-database '(<your stuff> <the standard stuff>))
978 ;; or, use `ps-print-hook' (see section Hooks):
979 ;; (add-hook 'ps-print-hook
981 ;; (or (assq 'Helvetica ps-font-info-database)
982 ;; (setq ps-font-info-database (append ...)))))
984 ;; You can create new `mixed' font families like:
986 ;; (fonts (normal . "Courier-Bold")
987 ;; (bold . "Helvetica")
988 ;; (italic . "ZapfChancery-MediumItalic")
989 ;; (bold-italic . "NewCenturySchlbk-BoldItalic")
990 ;; (w3-table-hack-x-face . "LineDrawNormal"))
992 ;; (line-height . 10.55)
993 ;; (space-width . 6.0)
994 ;; (avg-char-width . 6.0))
996 ;; Now you can use your new font family with any size:
997 ;; (setq ps-font-family 'my-mixed-family)
999 ;; Note that on above example the `w3-table-hack-x-face' entry refers to a face
1000 ;; symbol, so when printing this face it'll be used the font `LineDrawNormal'.
1001 ;; If the face `w3-table-hack-x-face' is remapped to use bold and/or italic
1002 ;; attribute, the corresponding entry (bold, italic or bold-italic) will be
1003 ;; used instead of `w3-table-hack-x-face' entry.
1005 ;; Note also that the font family entry order is irrelevant, so the above
1006 ;; example could also be written:
1009 ;; (fonts (w3-table-hack-x-face . "LineDrawNormal")
1010 ;; (bold . "Helvetica")
1011 ;; (bold-italic . "NewCenturySchlbk-BoldItalic")
1012 ;; (italic . "ZapfChancery-MediumItalic")
1013 ;; (normal . "Courier-Bold"))
1014 ;; (avg-char-width . 6.0)
1015 ;; (space-width . 6.0)
1016 ;; (line-height . 10.55))
1018 ;; Despite the note above, it is recommended that some convention about
1019 ;; entry order be used.
1021 ;; You can get information on all the fonts resident in YOUR printer
1022 ;; by uncommenting the line:
1023 ;; % 3 cm 20 cm moveto ReportAllFontInfo showpage
1025 ;; The PostScript file should be sent to YOUR PostScript printer.
1026 ;; If you send it to ghostscript or to another PostScript printer, you may get
1027 ;; slightly different results.
1028 ;; Anyway, as ghostscript fonts are autoload, you won't get much font info.
1030 ;; Note also that ps-print DOESN'T download any font to your printer, instead
1031 ;; it uses the fonts resident in your printer.
1034 ;; How Ps-Print Deals With Faces
1035 ;; -----------------------------
1037 ;; The ps-print-*-with-faces commands attempt to determine which faces should
1038 ;; be printed in bold or italic, but their guesses aren't always right. For
1039 ;; example, you might want to map colors into faces so that blue faces print in
1040 ;; bold, and red faces in italic.
1042 ;; It is possible to force ps-print to consider specific faces bold, italic or
1043 ;; underline, no matter what font they are displayed in, by setting the
1044 ;; variables `ps-bold-faces', `ps-italic-faces' and `ps-underlined-faces'.
1045 ;; These variables contain lists of faces that ps-print should consider bold,
1046 ;; italic or underline; to set them, put code like the following into your
1049 ;; (setq ps-bold-faces '(my-blue-face))
1050 ;; (setq ps-italic-faces '(my-red-face))
1051 ;; (setq ps-underlined-faces '(my-green-face))
1053 ;; Faces like bold-italic that are both bold and italic should go in *both*
1056 ;; ps-print keeps internal lists of which fonts are bold and which are italic;
1057 ;; these lists are built the first time you invoke ps-print.
1058 ;; For the sake of efficiency, the lists are built only once; the same lists
1059 ;; are referred in later invocations of ps-print.
1061 ;; Because these lists are built only once, it's possible for them to get out
1062 ;; of sync, if a face changes, or if new faces are added. To get the lists
1063 ;; back in sync, you can set the variable `ps-build-face-reference' to t, and
1064 ;; the lists will be rebuilt the next time ps-print is invoked. If you need
1065 ;; that the lists always be rebuilt when ps-print is invoked, set the variable
1066 ;; `ps-always-build-face-reference' to t.
1068 ;; If you need to print without worrying about face background color, set the
1069 ;; variable `ps-use-face-background' which specifies if face background should
1070 ;; be used. Valid values are:
1072 ;; t always use face background color.
1073 ;; nil never use face background color.
1074 ;; (face...) list of faces whose background color will be used.
1076 ;; Any other value will be treated as t.
1077 ;; The default value is nil.
1080 ;; How Ps-Print Deals With Color
1081 ;; -----------------------------
1083 ;; ps-print detects faces with foreground and background colors defined and
1084 ;; embeds color information in the PostScript image.
1085 ;; The default foreground and background colors are defined by the variables
1086 ;; `ps-default-fg' and `ps-default-bg'.
1087 ;; On black/white printers, colors are displayed in gray scale.
1088 ;; To turn off color output, set `ps-print-color-p' to nil.
1089 ;; You can also set `ps-print-color-p' to 'black-white to have a better looking
1090 ;; on black/white printers. See also `ps-black-white-faces' for documentation.
1093 ;; How Ps-Print Maps Faces
1094 ;; -----------------------
1096 ;; As ps-print uses PostScript to print buffers, it is possible to have other
1097 ;; attributes associated with faces. So the new attributes used by ps-print
1100 ;; strikeout - like underline, but the line is in middle of text.
1101 ;; overline - like underline, but the line is over the text.
1102 ;; shadow - text will have a shadow.
1103 ;; box - text will be surrounded by a box.
1104 ;; outline - print characters as hollow outlines.
1106 ;; See the documentation for `ps-extend-face'.
1108 ;; Let's, for example, remap `font-lock-keyword-face' to another foreground
1109 ;; color and bold attribute:
1111 ;; (ps-extend-face '(font-lock-keyword-face "RoyalBlue" nil bold) 'MERGE)
1113 ;; If you want to use a new face, define it first with `defface', and then call
1114 ;; `ps-extend-face' to specify how to print it.
1117 ;; How Ps-Print Has A Text And/Or Image On Background
1118 ;; --------------------------------------------------
1120 ;; ps-print can print texts and/or EPS PostScript images on background; it is
1121 ;; possible to define the following text attributes: font name, font size,
1122 ;; initial position, angle, gray scale and pages to print.
1124 ;; It has the following EPS PostScript images attributes: file name containing
1125 ;; the image, initial position, X and Y scales, angle and pages to print.
1127 ;; See documentation for `ps-print-background-text' and
1128 ;; `ps-print-background-image'.
1130 ;; For example, if we wish to print text "preliminary" on all pages and text
1131 ;; "special" on page 5 and from page 11 to page 17, we could specify:
1133 ;; (setq ps-print-background-text
1134 ;; '(("preliminary")
1136 ;; "LeftMargin" "BottomMargin PrintHeight add" ; X and Y position
1137 ;; ; (upper left corner)
1139 ;; "PrintHeight neg PrintPageWidth atan" ; angle
1140 ;; 5 (11 . 17)) ; page list
1143 ;; Similarly, we could print image "~/images/EPS-image1.ps" on all pages and
1144 ;; image "~/images/EPS-image2.ps" on page 5 and from page 11 to page 17, we
1147 ;; (setq ps-print-background-image
1148 ;; '(("~/images/EPS-image1.ps"
1149 ;; "LeftMargin" "BottomMargin") ; X and Y position (lower left corner)
1150 ;; ("~/images/EPS-image2.ps"
1151 ;; "LeftMargin" "BottomMargin PrintHeight 2 div add" ; X and Y pos.
1152 ;; ; (upper left corner)
1154 ;; 5 (11 . 17)) ; page list
1157 ;; If it is not possible to read (or does not exist) an image file, that file
1160 ;; The printing order is:
1162 ;; 1. Print background color
1163 ;; 2. Print zebra stripes
1164 ;; 3. Print background texts that it should be on all pages
1165 ;; 4. Print background images that it should be on all pages
1166 ;; 5. Print background texts only for current page (if any)
1167 ;; 6. Print background images only for current page (if any)
1169 ;; 8. Print buffer text (with faces, if specified) and line number
1175 ;; Some tools are provided to help you customize your font setup.
1177 ;; `ps-setup' returns (some part of) the current setup.
1179 ;; To avoid wrapping too many lines, you may want to adjust the left and right
1180 ;; margins and the font size. On UN*X systems, do:
1181 ;; pr -t file | awk '{printf "%3d %s\n", length($0), $0}' | sort -r | head
1182 ;; to determine the longest lines of your file.
1183 ;; Then, the command `ps-line-lengths' will give you the correspondence between
1184 ;; a line length (number of characters) and the maximum font size which doesn't
1185 ;; wrap such a line with the current ps-print setup.
1187 ;; The commands `ps-nb-pages-buffer' and `ps-nb-pages-region' display the
1188 ;; correspondence between a number of pages and the maximum font size which
1189 ;; allow the number of lines of the current buffer or of its current region to
1190 ;; fit in this number of pages.
1192 ;; NOTE: line folding is not taken into account in this process and could
1193 ;; change the results.
1195 ;; The command `ps-print-customize' activates a customization buffer for
1196 ;; ps-print options.
1199 ;; New since version 1.5
1200 ;; ---------------------
1202 ;; Color output capability.

1311 ;; --------------------------------------
1313 ;; Although color printing will work in XEmacs 19.12, it doesn't work well; in
1314 ;; particular, bold or italic fonts don't print in the right background color.
1316 ;; Invisible properties aren't correctly ignored in XEmacs 19.12.
1318 ;; Automatic font-attribute detection doesn't work well, especially with
1319 ;; hilit19 and older versions of get-create-face. Users having problems with
1320 ;; auto-font detection should use the lists `ps-italic-faces', `ps-bold-faces'
1321 ;; and `ps-underlined-faces' and/or turn off automatic detection by setting
1322 ;; `ps-auto-font-detect' to nil.
1324 ;; Automatic font-attribute detection doesn't work with XEmacs 19.12 in tty
1325 ;; mode; use the lists `ps-italic-faces', `ps-bold-faces' and
1326 ;; `ps-underlined-faces' instead.
1328 ;; Still too slow; could use some hand-optimization.
1330 ;; Default background color isn't working.
1332 ;; Faces are always treated as opaque.
1334 ;; Epoch, Lucid and Emacs 21 not supported. At all.
1336 ;; Fixed-pitch fonts work better for line folding, but are not required.
1338 ;; `ps-nb-pages-buffer' and `ps-nb-pages-region' don't take care of folding
1345 ;; Avoid page break inside a paragraph.
1346 ;; Add `ps-non-bold-faces' and `ps-non-italic-faces' (should be easy).
