49 ;; About ps-print
50 ;; --------------
52 ;; This package provides printing of Emacs buffers on PostScript printers;
53 ;; the buffer's bold and italic text attributes are preserved in the printer
54 ;; output. ps-print is intended for use with Emacs or Lucid Emacs, together
55 ;; with a fontifying package such as font-lock or hilit.
57 ;; ps-print uses the same face attributes defined through font-lock or hilit
58 ;; to print a PostScript file, but some faces are better seeing on the screen
59 ;; than on paper, specially when you have a black/white PostScript printer.
61 ;; ps-print allows a remap of face to another one that it is better to print,
62 ;; for example, the face font-lock-comment-face (if you are using font-lock)
63 ;; could have bold or italic attribute when printing, besides foreground color.
64 ;; This remap improves printing look (see How Ps-Print Maps Faces).
67 ;; Using ps-print
68 ;; --------------
70 ;; ps-print provides eight commands for generating PostScript images
71 ;; of Emacs buffers:
73 ;; ps-print-buffer
74 ;; ps-print-buffer-with-faces
75 ;; ps-print-region
76 ;; ps-print-region-with-faces
77 ;; ps-spool-buffer
78 ;; ps-spool-buffer-with-faces
79 ;; ps-spool-region
80 ;; ps-spool-region-with-faces
82 ;; These commands all perform essentially the same function: they
83 ;; generate PostScript images suitable for printing on a PostScript
84 ;; printer or displaying with GhostScript. These commands are
85 ;; collectively referred to as "ps-print- commands".
87 ;; The word "print" or "spool" in the command name determines when the
88 ;; PostScript image is sent to the printer:
90 ;; print - The PostScript image is immediately sent to the
91 ;; printer;
93 ;; spool - The PostScript image is saved temporarily in an
94 ;; Emacs buffer. Many images may be spooled locally
95 ;; before printing them. To send the spooled images
96 ;; to the printer, use the command `ps-despool'.
98 ;; The spooling mechanism was designed for printing lots of small
99 ;; files (mail messages or netnews articles) to save paper that would
100 ;; otherwise be wasted on banner pages, and to make it easier to find
101 ;; your output at the printer (it's easier to pick up one 50-page
102 ;; printout than to find 50 single-page printouts).
104 ;; ps-print has a hook in the `kill-emacs-hook' so that you won't
105 ;; accidentally quit from Emacs while you have unprinted PostScript
106 ;; waiting in the spool buffer. If you do attempt to exit with
107 ;; spooled PostScript, you'll be asked if you want to print it, and if
108 ;; you decline, you'll be asked to confirm the exit; this is modeled
109 ;; on the confirmation that Emacs uses for modified buffers.
111 ;; The word "buffer" or "region" in the command name determines how
112 ;; much of the buffer is printed:
114 ;; buffer - Print the entire buffer.
116 ;; region - Print just the current region.
118 ;; The -with-faces suffix on the command name means that the command
119 ;; will include font, color, and underline information in the
120 ;; PostScript image, so the printed image can look as pretty as the
121 ;; buffer. The ps-print- commands without the -with-faces suffix
122 ;; don't include font, color, or underline information; images printed
123 ;; with these commands aren't as pretty, but are faster to generate.
125 ;; Two ps-print- command examples:
127 ;; ps-print-buffer - print the entire buffer,
128 ;; without font, color, or
129 ;; underline information, and
130 ;; send it immediately to the
131 ;; printer.
133 ;; ps-spool-region-with-faces - print just the current region;
134 ;; include font, color, and
135 ;; underline information, and
136 ;; spool the image in Emacs to
137 ;; send to the printer later.
140 ;; Invoking Ps-Print
141 ;; -----------------
143 ;; To print your buffer, type
145 ;; M-x ps-print-buffer
147 ;; or substitute one of the other seven ps-print- commands. The
148 ;; command will generate the PostScript image and print or spool it as
149 ;; specified. By giving the command a prefix argument
151 ;; C-u M-x ps-print-buffer
153 ;; it will save the PostScript image to a file instead of sending it
154 ;; to the printer; you will be prompted for the name of the file to
155 ;; save the image to. The prefix argument is ignored by the commands
156 ;; that spool their images, but you may save the spooled images to a
157 ;; file by giving a prefix argument to `ps-despool':
159 ;; C-u M-x ps-despool
161 ;; When invoked this way, `ps-despool' will prompt you for the name of
162 ;; the file to save to.
164 ;; Any of the `ps-print-' commands can be bound to keys; I recommend
165 ;; binding `ps-spool-buffer-with-faces', `ps-spool-region-with-faces',
166 ;; and `ps-despool'. Here are the bindings I use on my Sun 4 keyboard:
168 ;; (global-set-key 'f22 'ps-spool-buffer-with-faces) ;f22 is prsc
169 ;; (global-set-key '(shift f22) 'ps-spool-region-with-faces)
170 ;; (global-set-key '(control f22) 'ps-despool)
173 ;; The Printer Interface
174 ;; ---------------------
176 ;; The variables `ps-lpr-command' and `ps-lpr-switches' determine what
177 ;; command is used to send the PostScript images to the printer, and
178 ;; what arguments to give the command. These are analogous to
179 ;; `lpr-command' and `lpr-switches'.
181 ;; Make sure that they contain appropriate values for your system;
182 ;; see the usage notes below and the documentation of these variables.
184 ;; The variable `ps-printer-name' determines the name of a local printer for
185 ;; printing PostScript files.
187 ;; The variable `ps-printer-name-option' determines the option used by some
188 ;; utilities to indicate the printer name, it's used only when
189 ;; `ps-printer-name' is a non-empty string. If you're using lpr utility to
190 ;; print, for example, `ps-printer-name-option' should be set to "-P".
192 ;; NOTE: `ps-lpr-command' and `ps-lpr-switches' take their initial values
193 ;; from the variables `lpr-command' and `lpr-switches'. If you have
194 ;; `lpr-command' set to invoke a pretty-printer such as `enscript',
195 ;; then ps-print won't work properly. `ps-lpr-command' must name
196 ;; a program that does not format the files it prints.
197 ;; `ps-printer-name' takes its initial value from the variable
198 ;; `printer-name'. `ps-printer-name-option' tries to guess which system
199 ;; Emacs is running and takes its initial value in accordance with this
200 ;; guess.
202 ;; The variable `ps-print-region-function' specifies a function to print the
203 ;; region on a PostScript printer.
204 ;; See definition of `call-process-region' for calling conventions. The fourth
205 ;; and the sixth arguments are both nil.
207 ;; The variable `ps-manual-feed' indicates if the printer will manually feed
208 ;; paper. If it's nil, automatic feeding takes place. If it's non-nil, manual
209 ;; feeding takes place. The default is nil (automatic feeding).
211 ;; The variable `ps-end-with-control-d' specifies whether C-d (\x04) should be
212 ;; inserted at end of PostScript generated. Non-nil means do so. The default
213 ;; is nil (don't insert).
215 ;; If you're using Emacs for Windows 95/98/NT or MS-DOS, don't forget to
216 ;; customize the following variables: `ps-printer-name',
217 ;; `ps-printer-name-option', `ps-lpr-command', `ps-lpr-switches' and
218 ;; `ps-spool-config'. See these variables documentation in the code or by
219 ;; typing, for example, C-h v ps-printer-name RET.
222 ;; The Page Layout
223 ;; ---------------
225 ;; All dimensions are floats in PostScript points.
226 ;; 1 inch == 2.54 cm == 72 points
227 ;; 1 cm == (/ 1 2.54) inch == (/ 72 2.54) points
229 ;; The variable `ps-paper-type' determines the size of paper ps-print formats
230 ;; for; it should contain one of the symbols: `a4' `a3' `letter' `legal'
231 ;; `letter-small' `tabloid' `ledger' `statement' `executive' `a4small' `b4'
232 ;; `b5'.
234 ;; If variable `ps-warn-paper-type' is nil, it's *not* given an error if
235 ;; PostScript printer doesn't have a paper with the size indicated by
236 ;; `ps-paper-type', instead it uses the default paper size. If variable
237 ;; `ps-warn-paper-type' is non-nil, it's given an error if PostScript printer
238 ;; doesn't have a paper with the size indicated by `ps-paper-type'. It's used
239 ;; when `ps-spool-config' is set to `setpagedevice' (see section Duplex
240 ;; Printers). The default value is non-nil (it gives an error).
242 ;; The variable `ps-landscape-mode' determines the orientation of the printing
243 ;; on the page: nil means `portrait' mode, non-nil means `landscape' mode.
244 ;; There is no oblique mode yet, though this is easy to do in ps.
246 ;; In landscape mode, the text is NOT scaled: you may print 70 lines in portrait
247 ;; mode and only 50 lines in landscape mode. The margins represent margins in
248 ;; the printed paper: the top margin is the margin between the top of the page
249 ;; and the printed header, whatever the orientation is.
251 ;; The variable `ps-number-of-columns' determines the number of columns both in
252 ;; landscape and portrait mode.
253 ;; You can use:
254 ;; - (the standard) one column portrait mode.
255 ;; - (my favorite) two columns landscape mode (which spares trees).
256 ;; but also:
257 ;; - one column landscape mode for files with very long lines.
258 ;; - multi-column portrait or landscape mode.
260 ;; The variable `ps-print-upside-down' determines other orientation for printing
261 ;; page: nil means `normal' printing, non-nil means `upside-down' printing. The
262 ;; default value is nil (`normal' printing).
264 ;; The `upside-down' orientation can be used in portrait or landscape mode.
266 ;; The variable `ps-selected-pages' specifies which pages to print. If it's
267 ;; nil, all pages are printed. If it's a list, the list element may be an
268 ;; integer or a cons cell (FROM . TO) designating FROM page to TO page; any
269 ;; invalid element is ignored, that is, an integer lesser than one or if FROM
270 ;; is greater than TO. Otherwise, it's treated as nil. The default value is
271 ;; nil (print all pages). After ps-print processing `ps-selected-pages' is set
272 ;; to nil. But the latest `ps-selected-pages' is saved in
273 ;; `ps-last-selected-pages' (see it for documentation). So you can restore the
274 ;; latest selected pages by using `ps-last-selected-pages' or by calling
275 ;; `ps-restore-selected-pages' command (see it for documentation).
277 ;; The variable `ps-even-or-odd-pages' specifies if it prints even/odd pages.
279 ;; Valid values are:
281 ;; nil print all pages.
283 ;; even-page print only even pages.
285 ;; odd-page print only odd pages.
287 ;; even-sheet print only even sheets.
289 ;; odd-sheet print only odd sheets.
291 ;; Any other value is treated as nil. The default value is nil.
293 ;; See `ps-even-or-odd-pages' for more detailed documentation.
296 ;; Horizontal layout
297 ;; -----------------
299 ;; The horizontal layout is determined by the variables
300 ;; `ps-left-margin' `ps-inter-column' `ps-right-margin'
301 ;; as follows:
303 ;; ------------------------------------------
304 ;; | | | | | | | |
305 ;; | lm | text | ic | text | ic | text | rm |
306 ;; | | | | | | | |
307 ;; ------------------------------------------
309 ;; If `ps-number-of-columns' is 1, `ps-inter-column' is not relevant.
310 ;; Usually, lm = rm > 0 and ic = lm
311 ;; If (ic < 0), the text of adjacent columns can overlap.
314 ;; Vertical layout
315 ;; ---------------
317 ;; The vertical layout is determined by the variables
318 ;; `ps-bottom-margin' `ps-top-margin' `ps-header-offset'
319 ;; as follows:
321 ;; |--------| |--------|
322 ;; | tm | | tm |
323 ;; |--------| |--------|
324 ;; | header | | |
325 ;; |--------| | |
326 ;; | ho | | |
327 ;; |--------| or | text |
328 ;; | | | |
329 ;; | text | | |
330 ;; | | | |
331 ;; |--------| |--------|
332 ;; | bm | | bm |
333 ;; |--------| |--------|
335 ;; If `ps-print-header' is nil, `ps-header-offset' is not relevant.
336 ;; The margins represent margins in the printed paper:
337 ;; the top margin is the margin between the top of the page
338 ;; and the printed header, whatever the orientation is.
341 ;; Headers
342 ;; -------
344 ;; ps-print can print headers at the top of each column or at the top
345 ;; of each page; the default headers contain the following four items:
346 ;; on the left, the name of the buffer and, if the buffer is visiting
347 ;; a file, the file's directory; on the right, the page number and
348 ;; date of printing. The default headers look something like this:
350 ;; ps-print.el 1/21
351 ;; /home/jct/emacs-lisp/ps/new 94/12/31
353 ;; When printing on duplex printers, left and right are reversed so
354 ;; that the 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 ;; To print only one header at the top of each page,
362 ;; set `ps-print-only-one-header' to t.
364 ;; To switch headers, set `ps-switch-header' to:
366 ;; nil Never switch headers.
368 ;; t Always switch headers.
370 ;; duplex Switch headers only when duplexing is on, that is, when
371 ;; `ps-spool-duplex' is non-nil (see Duplex Printers).
373 ;; Any other value is treated as t. The default value is `duplex'.
375 ;; The font family and size of text in the header are determined
376 ;; by the variables `ps-header-font-family', `ps-header-font-size' and
377 ;; `ps-header-title-font-size' (see below).
379 ;; The variable `ps-header-line-pad' determines the portion of a header
380 ;; title line height to insert between the header frame and the text
381 ;; it contains, both in the vertical and horizontal directions:
382 ;; .5 means half a line.
384 ;; Page numbers are printed in `n/m' format, indicating page n of m pages;
385 ;; to omit the total page count and just print the page number,
386 ;; set `ps-show-n-of-n' to nil.
388 ;; The amount of information in the header can be changed by changing
389 ;; the number of lines. To show less, set `ps-header-lines' to 1, and
390 ;; the header will show only the buffer name and page number. To show
391 ;; more, set `ps-header-lines' to 3, and the header will show the time of
392 ;; printing below the date.
394 ;; To change the content of the headers, change the variables
395 ;; `ps-left-header' and `ps-right-header'.
396 ;; These variables are lists, specifying top-to-bottom the text
397 ;; to display on the left or right side of the header.
398 ;; Each element of the list should be a string or a symbol.
399 ;; Strings are inserted directly into the PostScript arrays,
400 ;; and should contain the PostScript string delimiters '(' and ')'.
402 ;; Symbols in the header format lists can either represent functions
403 ;; or variables. Functions are called, and should return a string to
404 ;; show in the header. Variables should contain strings to display in
405 ;; the header. In either case, function or variable, the PostScript
406 ;; string delimiters are added by ps-print, and should not be part of
407 ;; the returned value.
409 ;; Here's an example: say we want the left header to display the text
411 ;; Moe
412 ;; Larry
413 ;; Curly
415 ;; where we have a function to return "Moe"
417 ;; (defun moe-func ()
418 ;; "Moe")
420 ;; a variable specifying "Larry"
422 ;; (setq larry-var "Larry")
424 ;; and a literal for "Curly". Here's how `ps-left-header' should be
425 ;; set:
427 ;; (setq ps-left-header (list 'moe-func 'larry-var "(Curly)"))
429 ;; Note that Curly has the PostScript string delimiters inside his
430 ;; quotes -- those aren't misplaced lisp delimiters!
432 ;; Without them, PostScript would attempt to call the undefined
433 ;; function Curly, which would result in a PostScript error.
435 ;; Since most printers don't report PostScript errors except by
436 ;; aborting the print job, this kind of error can be hard to track down.
438 ;; Consider yourself warned!
441 ;; PostScript Prologue Header
442 ;; --------------------------
444 ;; It is possible to add PostScript prologue header comments besides that
445 ;; ps-print generates by setting the variable `ps-print-prologue-header'.
447 ;; `ps-print-prologue-header' may be a string or a symbol function which returns
448 ;; a string. Note that this string is inserted on PostScript prologue header
449 ;; section which is used to define some document characteristic through
450 ;; PostScript special comments, like "%%Requirements: jog\n".
452 ;; By default `ps-print-prologue-header' is nil.
454 ;; ps-print always inserts the %%Requirements: comment, so if you need to insert
455 ;; more requirements put them first in `ps-print-prologue-header' using the
456 ;; "%%+" comment. For example, if you need to set numcopies to 3 and jog on
457 ;; requirements and set %%LanguageLevel: to 2, do:
459 ;; (setq ps-print-prologue-header
460 ;; "%%+ numcopies(3) jog\n%%LanguageLevel: 2\n")
462 ;; The duplex requirement is inserted by ps-print (see section Duplex Printers).
464 ;; Do not forget to terminate the string with "\n".
466 ;; For more information about PostScript document comments, see:
467 ;; PostScript Language Reference Manual (2nd edition)
468 ;; Adobe Systems Incorporated
469 ;; Appendix G: Document Structuring Conventions -- Version 3.0
471 ;; It is also possible to add an user defined PostScript prologue code before
472 ;; all generated prologue code by setting the variable
473 ;; `ps-user-defined-prologue'.
475 ;; `ps-user-defined-prologue' may be a string or a symbol function which returns
476 ;; a string. Note that this string is inserted after `ps-adobe-tag' and
477 ;; PostScript prologue comments, and before ps-print PostScript prologue code
478 ;; section. That is, this string is inserted after error handler initialization
479 ;; and before ps-print settings.
481 ;; By default `ps-user-defined-prologue' is nil.
483 ;; It's strongly recommended only insert PostScript code and/or comments
484 ;; specific for your printing system particularities. For example, some special
485 ;; initialization that only your printing system needs.
487 ;; Do not insert code for duplex printing, n-up printing or error handler,
488 ;; ps-print handles this in a suitable way.
490 ;; For more information about PostScript, see:
491 ;; PostScript Language Reference Manual (2nd edition)
492 ;; Adobe Systems Incorporated
494 ;; As an example for `ps-user-defined-prologue' setting:
496 ;; ;; Setting for HP PostScript printer
497 ;; (setq ps-user-defined-prologue
498 ;; (concat "<</DeferredMediaSelection true /PageSize [612 792] "
499 ;; "/MediaPosition 2 /MediaType (Plain)>> setpagedevice"))
502 ;; PostScript Error Handler
503 ;; ------------------------
505 ;; ps-print instruments generated PostScript code with an error handler.
507 ;; The variable `ps-error-handler-message' specifies where the error handler
508 ;; message should be sent.
510 ;; Valid values are:
512 ;; none catch the error and *DON'T* send any message.
514 ;; paper catch the error and print on paper the error message.
515 ;; This is the default value.
517 ;; system catch the error and send back the error message to
518 ;; printing system. This is useful only if printing system
519 ;; send back an email reporting the error, or if there is
520 ;; some other alternative way to report back the error from
521 ;; the system to you.
523 ;; paper-and-system catch the error, print on paper the error message and
524 ;; send back the error message to printing system.
526 ;; Any other value is treated as `paper'.
529 ;; Duplex Printers
530 ;; ---------------
532 ;; If you have a duplex-capable printer (one that prints both sides of the
533 ;; paper), set `ps-spool-duplex' to t.
534 ;; ps-print will insert blank pages to make sure each buffer starts on the
535 ;; correct side of the paper.
537 ;; The variable `ps-spool-config' specifies who is the responsable for setting
538 ;; duplex and page size switches. Valid values are:
540 ;; lpr-switches duplex and page size are configured by `ps-lpr-switches'.
541 ;; Don't forget to set `ps-lpr-switches' to select duplex
542 ;; printing for your printer.
544 ;; setpagedevice duplex and page size are configured by ps-print using the
545 ;; setpagedevice PostScript operator.
547 ;; nil duplex and page size are configured by ps-print *not* using
548 ;; the setpagedevice PostScript operator.
550 ;; Any other value is treated as nil.
552 ;; The default value is `lpr-switches'.
554 ;; WARNING: The setpagedevice PostScript operator affects ghostview utility when
555 ;; viewing file generated using landscape. Also on some printers,
556 ;; setpagedevice affects zebra stripes; on other printers,
557 ;; setpagedevice affects the left margin.
558 ;; Besides all that, if your printer does not have the paper size
559 ;; specified by setpagedevice, your printing will be aborted.
560 ;; So, if you need to use setpagedevice, set `ps-spool-config' to
561 ;; `setpagedevice', generate a test file and send it to your printer;
562 ;; if the printed file isn't ok, set `ps-spool-config' to nil.
564 ;; The variable `ps-spool-tumble' specifies how the page images on opposite
565 ;; sides of a sheet are oriented with respect to each other. If
566 ;; `ps-spool-tumble' is nil, produces output suitable for binding on the left or
567 ;; right. If `ps-spool-tumble' is non-nil, produces output suitable for binding
568 ;; at the top or bottom. It has effect only when `ps-spool-duplex' is non-nil.
569 ;; The default value is nil.
571 ;; Some printer system prints a header page and forces the first page be printed
572 ;; on header page back, when using duplex. If your printer system has this
573 ;; behavior, set variable `ps-banner-page-when-duplexing' to t.
575 ;; When `ps-banner-page-when-duplexing' is non-nil means the very first page is
576 ;; skipped. It's like the very first character of buffer (or region) is ^L
577 ;; (\014).
579 ;; The default for `ps-banner-page-when-duplexing' is nil (*don't* skip the very
580 ;; first page).
583 ;; N-up Printing
584 ;; -------------
586 ;; The variable `ps-n-up-printing' specifies the number of pages per sheet of
587 ;; paper. The value specified must be between 1 and 100. The default is 1.
589 ;; NOTE: some PostScript printer may crash printing if `ps-n-up-printing' is set
590 ;; to a high value (for example, 23). If this happens, set a lower value.
592 ;; The variable `ps-n-up-margin' specifies the margin in points between the
593 ;; sheet border and the n-up printing. The default is 1 cm (or 0.3937 inches,
594 ;; or 28.35 points).
596 ;; If variable `ps-n-up-border-p' is non-nil a border is drawn around each page.
597 ;; The default is t.
599 ;; The variable `ps-n-up-filling' specifies how page matrix is filled on each
600 ;; sheet of paper. Following are the valid values for `ps-n-up-filling' with a
601 ;; filling example using a 3x4 page matrix:
603 ;; left-top 1 2 3 4 left-bottom 9 10 11 12
604 ;; 5 6 7 8 5 6 7 8
605 ;; 9 10 11 12 1 2 3 4
607 ;; right-top 4 3 2 1 right-bottom 12 11 10 9
608 ;; 8 7 6 5 8 7 6 5
609 ;; 12 11 10 9 4 3 2 1
611 ;; top-left 1 4 7 10 bottom-left 3 6 9 12
612 ;; 2 5 8 11 2 5 8 11
613 ;; 3 6 9 12 1 4 7 10
615 ;; top-right 10 7 4 1 bottom-right 12 9 6 3
616 ;; 11 8 5 2 11 8 5 2
617 ;; 12 9 6 3 10 7 4 1
619 ;; Any other value is treated as left-top.
621 ;; The default value is left-top.
624 ;; Control And 8-bit Characters
625 ;; ----------------------------
627 ;; The variable `ps-print-control-characters' specifies whether you want to see
628 ;; a printable form for control and 8-bit characters, that is, instead of
629 ;; sending, for example, a ^D (\004) to printer, it is sent the string "^D".
631 ;; Valid values for `ps-print-control-characters' are:
633 ;; 8-bit This is the value to use when you want an ASCII encoding of
634 ;; any control or non-ASCII character. Control characters are
635 ;; encoded as "^D", and non-ASCII characters have an
636 ;; octal encoding.
638 ;; control-8-bit This is the value to use when you want an ASCII encoding of
639 ;; any control character, whether it is 7 or 8-bit.
640 ;; European 8-bits accented characters are printed according
641 ;; the current font.
643 ;; control Only ASCII control characters have an ASCII encoding.
644 ;; European 8-bits accented characters are printed according
645 ;; the current font.
647 ;; nil No ASCII encoding. Any character is printed according the
648 ;; current font.
650 ;; Any other value is treated as nil.
652 ;; The default is `control-8-bit'.
654 ;; Characters TAB, NEWLINE and FORMFEED are always treated by ps-print engine.
657 ;; Printing Multi-byte Buffer
658 ;; --------------------------
660 ;; See ps-mule.el for documentation.
663 ;; Line Number
664 ;; -----------
666 ;; The variable `ps-line-number' specifies whether to number each line;
667 ;; non-nil means do so. The default is nil (don't number each line).
669 ;; The variable `ps-line-number-font' specifies the font for line number.
670 ;; The default is "Times-Italic".
672 ;; The variable `ps-line-number-font-size' specifies the font size in points
673 ;; for line number. See `ps-font-size' for documentation. The default is 6.
675 ;; The variable `ps-line-number-step' specifies the interval that line number is
676 ;; printed. For example, if `ps-line-number-step' is set to 2, the printing
677 ;; will look like:
679 ;; 1 one line
680 ;; one line
681 ;; 3 one line
682 ;; one line
683 ;; 5 one line
684 ;; one line
685 ;; ...
687 ;; Valid values are:
689 ;; integer an integer that specifies the interval that line number is
690 ;; printed. If it's lesser than or equal to zero, it's used the
691 ;; value 1.
693 ;; `zebra' specifies that only the line number of the first line in a zebra
694 ;; stripe is to be printed.
696 ;; Any other value is treated as `zebra'.
697 ;; The default value is 1, so each line number is printed.
699 ;; The variable `ps-line-number-start' specifies the starting point in the
700 ;; interval given by `ps-line-number-step'. For example, if
701 ;; `ps-line-number-step' is set to 3 and `ps-line-number-start' is set to 3, the
702 ;; printing will look like:
704 ;; one line
705 ;; one line
706 ;; 3 one line
707 ;; one line
708 ;; one line
709 ;; 6 one line
710 ;; one line
711 ;; one line
712 ;; 9 one line
713 ;; one line
714 ;; ...
716 ;; The values for `ps-line-number-start':
718 ;; * If `ps-line-number-step' is an integer, must be between 1 and the value
719 ;; of `ps-line-number-step' inclusive.
721 ;; * If `ps-line-number-step' is set to `zebra', must be between 1 and the
722 ;; value of `ps-zebra-stripe-height' inclusive.
724 ;; The default value is 1, so the line number of the first line of each interval
725 ;; is printed.
728 ;; Zebra Stripes
729 ;; -------------
731 ;; Zebra stripes are a kind of background that appear "underneath" the text
732 ;; and can make the text easier to read. They look like this:
734 ;; XXXXXXXXXXXXXXXXXXXXXXXX
735 ;; XXXXXXXXXXXXXXXXXXXXXXXX
736 ;; XXXXXXXXXXXXXXXXXXXXXXXX
740 ;; XXXXXXXXXXXXXXXXXXXXXXXX
741 ;; XXXXXXXXXXXXXXXXXXXXXXXX
742 ;; XXXXXXXXXXXXXXXXXXXXXXXX
744 ;; The blocks of X's represent rectangles filled with a light gray color.
745 ;; Each rectangle extends all the way across the page.
747 ;; The height, in lines, of each rectangle is controlled by
748 ;; the variable `ps-zebra-stripe-height', which is 3 by default.
749 ;; The distance between stripes equals the height of a stripe.
751 ;; The variable `ps-zebra-stripes' controls whether to print zebra stripes.
752 ;; Non-nil means yes, nil means no. The default is nil.
754 ;; The variable `ps-zebra-color' controls the zebra stripes gray scale or RGB
755 ;; color. It should be a float number between 0.0 (black color) and 1.0 (white
756 ;; color), a string which is a color name, or a list of 3 numbers which
757 ;; corresponds to the Red Green Blue color scale.
758 ;; The default is 0.95 (or "gray95", or '(0.95 0.95 0.95)).
760 ;; The variable `ps-zebra-stripe-follow' specifies if zebra stripe should
761 ;; continue on next page or restart on each page. If `ps-zebra-stripe-follow'
762 ;; is nil, zebra stripe is restarted on each page. If `ps-zebra-stripe-follow'
763 ;; is non-nil, zebra stripe continues on next page. Visually, we have:
765 ;; `ps-zebra-stripe-follow' `ps-zebra-stripe-follow'
766 ;; is nil is non-nil
767 ;; Current Page ------------------------ ------------------------

788 ;; See also section How Ps-Print Has A Text And/Or Image On Background.
791 ;; Hooks
792 ;; -----
794 ;; ps-print has the following hook variables:
796 ;; `ps-print-hook'
797 ;; It is evaluated once before any printing process. This is the right
798 ;; place to initialize ps-print global data.
799 ;; For an example, see section Adding a New Font Family.
801 ;; `ps-print-begin-sheet-hook'
802 ;; It is evaluated on each beginning of sheet of paper.
803 ;; If `ps-n-up-printing' is equal to 1, `ps-print-begin-page-hook' is never
804 ;; evaluated.
806 ;; `ps-print-begin-page-hook'
807 ;; It is evaluated on each beginning of page, except in the beginning
808 ;; of page that `ps-print-begin-sheet-hook' is evaluated.
810 ;; `ps-print-begin-column-hook'
811 ;; It is evaluated on each beginning of column, except in the beginning
812 ;; of column that `ps-print-begin-page-hook' is evaluated or that
813 ;; `ps-print-begin-sheet-hook' is evaluated.
816 ;; Font Managing
817 ;; -------------
819 ;; ps-print now knows rather precisely some fonts: the variable
820 ;; `ps-font-info-database' contains information for a list of font families
821 ;; (currently mainly `Courier' `Helvetica' `Times' `Palatino' `Helvetica-Narrow'
822 ;; `NewCenturySchlbk'). Each font family contains the font names for standard,
823 ;; bold, italic and bold-italic characters, a reference size (usually 10) and
824 ;; the corresponding line height, width of a space and average character width.
826 ;; The variable `ps-font-family' determines which font family is to be used for
827 ;; ordinary text. If its value does not correspond to a known font family, an
828 ;; error message is printed into the `*Messages*' buffer, which lists the
829 ;; currently available font families.
831 ;; The variable `ps-font-size' determines the size (in points) of the font for
832 ;; ordinary text, when generating PostScript. Its value is a float or a cons of
833 ;; floats which has the following form:
835 ;; (LANDSCAPE-SIZE . PORTRAIT-SIZE)
837 ;; Similarly, the variable `ps-header-font-family' determines which font family
838 ;; is to be used for text in the header.
840 ;; The variable `ps-header-font-size' determines the font size, in points, for
841 ;; text in the header (similar to `ps-font-size').
843 ;; The variable `ps-header-title-font-size' determines the font size, in points,
844 ;; for the top line of text in the header (similar to `ps-font-size').
847 ;; Adding a New Font Family
848 ;; ------------------------
850 ;; To use a new font family, you MUST first teach ps-print
851 ;; this font, i.e., add its information to `ps-font-info-database',
852 ;; otherwise ps-print cannot correctly place line and page breaks.
854 ;; For example, assuming `Helvetica' is unknown,
855 ;; you first need to do the following ONLY ONCE:
857 ;; - create a new buffer
858 ;; - generate the PostScript image to a file (C-u M-x ps-print-buffer)
859 ;; - open this file and find the line:
860 ;; `% 3 cm 20 cm moveto 10/Courier ReportFontInfo showpage'
861 ;; - delete the leading `%' (which is the PostScript comment character)
862 ;; - replace in this line `Courier' by the new font (say `Helvetica')
863 ;; to get the line:
864 ;; `3 cm 20 cm moveto 10/Helvetica ReportFontInfo showpage'
865 ;; - send this file to the printer (or to ghostscript).
866 ;; You should read the following on the output page:
868 ;; For Helvetica 10 point, the line height is 11.56, the space width is 2.78
869 ;; and a crude estimate of average character width is 5.09243
871 ;; - Add these values to the `ps-font-info-database':
872 ;; (setq ps-font-info-database
873 ;; (append
874 ;; '((Helvetica ; the family key
875 ;; (fonts (normal . "Helvetica")
876 ;; (bold . "Helvetica-Bold")
877 ;; (italic . "Helvetica-Oblique")
878 ;; (bold-italic . "Helvetica-BoldOblique"))
879 ;; (size . 10.0)
880 ;; (line-height . 11.56)
881 ;; (space-width . 2.78)
882 ;; (avg-char-width . 5.09243)))
883 ;; ps-font-info-database))
884 ;; - Now you can use this font family with any size:
885 ;; (setq ps-font-family 'Helvetica)
886 ;; - if you want to use this family in another emacs session, you must
887 ;; put into your `~/.emacs':
888 ;; (require 'ps-print)
889 ;; (setq ps-font-info-database (append ...)))
890 ;; if you don't want to load ps-print, you have to copy the whole value:
891 ;; (setq ps-font-info-database '(<your stuff> <the standard stuff>))
892 ;; or, use `ps-print-hook' (see section Hooks):
893 ;; (add-hook 'ps-print-hook
894 ;; '(lambda ()
895 ;; (or (assq 'Helvetica ps-font-info-database)
896 ;; (setq ps-font-info-database (append ...)))))
898 ;; You can create new `mixed' font families like:
899 ;; (my-mixed-family
900 ;; (fonts (normal . "Courier-Bold")
901 ;; (bold . "Helvetica")
902 ;; (italic . "Zapf-Chancery-MediumItalic")
903 ;; (bold-italic . "NewCenturySchlbk-BoldItalic")
904 ;; (w3-table-hack-x-face . "LineDrawNormal"))
905 ;; (size . 10.0)
906 ;; (line-height . 10.55)
907 ;; (space-width . 6.0)
908 ;; (avg-char-width . 6.0))
910 ;; Now you can use your new font family with any size:
911 ;; (setq ps-font-family 'my-mixed-family)
913 ;; Note that on above example the `w3-table-hack-x-face' entry refers to
914 ;; a face symbol, so when printing this face it'll be used the font
915 ;; `LineDrawNormal'. If the face `w3-table-hack-x-face' is remapped to
916 ;; use bold and/or italic attribute, the corresponding entry (bold, italic
917 ;; or bold-italic) will be used instead of `w3-table-hack-x-face' entry.
919 ;; Note also that the font family entry order is irrelevant, so the above
920 ;; example could also be written:
921 ;; (my-mixed-family
922 ;; (size . 10.0)
923 ;; (fonts (w3-table-hack-x-face . "LineDrawNormal")
924 ;; (bold . "Helvetica")
925 ;; (bold-italic . "NewCenturySchlbk-BoldItalic")
926 ;; (italic . "Zapf-Chancery-MediumItalic")
927 ;; (normal . "Courier-Bold"))
928 ;; (avg-char-width . 6.0)
929 ;; (space-width . 6.0)
930 ;; (line-height . 10.55))
932 ;; Despite the note above, it is recommended that some convention about
933 ;; entry order be used.
935 ;; You can get information on all the fonts resident in YOUR printer
936 ;; by uncommenting the line:
937 ;; % 3 cm 20 cm moveto ReportAllFontInfo showpage
939 ;; The PostScript file should be sent to YOUR PostScript printer.
940 ;; If you send it to ghostscript or to another PostScript printer,
941 ;; you may get slightly different results.
942 ;; Anyway, as ghostscript fonts are autoload, you won't get much font info.
944 ;; Note also that ps-print DOESN'T download any font to your printer, instead
945 ;; it uses the fonts resident in your printer.
948 ;; How Ps-Print Deals With Faces
949 ;; -----------------------------
951 ;; The ps-print-*-with-faces commands attempt to determine which faces
952 ;; should be printed in bold or italic, but their guesses aren't
953 ;; always right. For example, you might want to map colors into faces
954 ;; so that blue faces print in bold, and red faces in italic.
956 ;; It is possible to force ps-print to consider specific faces bold,
957 ;; italic or underline, no matter what font they are displayed in, by setting
958 ;; the variables `ps-bold-faces', `ps-italic-faces' and `ps-underlined-faces'.
959 ;; These variables contain lists of faces that ps-print should consider bold,
960 ;; italic or underline; to set them, put code like the following into your
961 ;; .emacs file:
963 ;; (setq ps-bold-faces '(my-blue-face))
964 ;; (setq ps-italic-faces '(my-red-face))
965 ;; (setq ps-underlined-faces '(my-green-face))
967 ;; Faces like bold-italic that are both bold and italic should go in
968 ;; *both* lists.
970 ;; ps-print keeps internal lists of which fonts are bold and which are
971 ;; italic; these lists are built the first time you invoke ps-print.
972 ;; For the sake of efficiency, the lists are built only once; the same
973 ;; lists are referred in later invocations of ps-print.
975 ;; Because these lists are built only once, it's possible for them to
976 ;; get out of sync, if a face changes, or if new faces are added. To
977 ;; get the lists back in sync, you can set the variable
978 ;; `ps-build-face-reference' to t, and the lists will be rebuilt the
979 ;; next time ps-print is invoked. If you need that the lists always be
980 ;; rebuilt when ps-print is invoked, set the variable
981 ;; `ps-always-build-face-reference' to t.
983 ;; If you need to print without worrying about face background color, set the
984 ;; variable `ps-use-face-background' which specifies if face background should
985 ;; be used. Valid values are:
987 ;; t always use face background color.
988 ;; nil never use face background color.
989 ;; (face...) list of faces whose background color will be used.
991 ;; Any other value will be treated as t.
992 ;; The default value is t.
995 ;; How Ps-Print Deals With Color
996 ;; -----------------------------
998 ;; ps-print detects faces with foreground and background colors
999 ;; defined and embeds color information in the PostScript image.
1000 ;; The default foreground and background colors are defined by the
1001 ;; variables `ps-default-fg' and `ps-default-bg'.
1002 ;; On black-and-white printers, colors are displayed in gray scale.
1003 ;; To turn off color output, set `ps-print-color-p' to nil.
1006 ;; How Ps-Print Maps Faces
1007 ;; -----------------------
1009 ;; As ps-print uses PostScript to print buffers, it is possible to have
1010 ;; other attributes associated with faces. So the new attributes used
1011 ;; by ps-print are:
1013 ;; strikeout - like underline, but the line is in middle of text.
1014 ;; overline - like underline, but the line is over the text.
1015 ;; shadow - text will have a shadow.
1016 ;; box - text will be surrounded by a box.
1017 ;; outline - print characters as hollow outlines.
1019 ;; See the documentation for `ps-extend-face'.
1021 ;; Let's, for example, remap `font-lock-keyword-face' to another foreground
1022 ;; color and bold attribute:
1024 ;; (ps-extend-face '(font-lock-keyword-face "RoyalBlue" nil bold) 'MERGE)
1026 ;; If you want to use a new face, define it first with `defface',
1027 ;; and then call `ps-extend-face' to specify how to print it.
1030 ;; How Ps-Print Has A Text And/Or Image On Background
1031 ;; --------------------------------------------------
1033 ;; ps-print can print texts and/or EPS PostScript images on background; it is
1034 ;; possible to define the following text attributes: font name, font size,
1035 ;; initial position, angle, gray scale and pages to print.
1037 ;; It has the following EPS PostScript images attributes: file name containing
1038 ;; the image, initial position, X and Y scales, angle and pages to print.
1040 ;; See documentation for `ps-print-background-text' and
1041 ;; `ps-print-background-image'.
1043 ;; For example, if we wish to print text "preliminary" on all pages and text
1044 ;; "special" on page 5 and from page 11 to page 17, we could specify:
1046 ;; (setq ps-print-background-text
1047 ;; '(("preliminary")
1048 ;; ("special"
1049 ;; "LeftMargin" "BottomMargin PrintHeight add" ; X and Y position
1050 ;; ; (upper left corner)
1051 ;; nil nil nil
1052 ;; "PrintHeight neg PrintPageWidth atan" ; angle
1053 ;; 5 (11 . 17)) ; page list
1054 ;; ))
1056 ;; Similarly, we could print image "~/images/EPS-image1.ps" on all pages and
1057 ;; image "~/images/EPS-image2.ps" on page 5 and from page 11 to page 17, we
1058 ;; specify:
1060 ;; (setq ps-print-background-image
1061 ;; '(("~/images/EPS-image1.ps"
1062 ;; "LeftMargin" "BottomMargin") ; X and Y position (lower left corner)
1063 ;; ("~/images/EPS-image2.ps"
1064 ;; "LeftMargin" "BottomMargin PrintHeight 2 div add" ; X and Y position
1065 ;; ; (upper left corner)
1066 ;; nil nil nil
1067 ;; 5 (11 . 17)) ; page list
1068 ;; ))
1070 ;; If it is not possible to read (or does not exist) an image file, that file
1071 ;; is ignored.
1073 ;; The printing order is:
1075 ;; 1. Print background color
1076 ;; 2. Print zebra stripes
1077 ;; 3. Print background texts that it should be on all pages
1078 ;; 4. Print background images that it should be on all pages
1079 ;; 5. Print background texts only for current page (if any)
1080 ;; 6. Print background images only for current page (if any)
1081 ;; 7. Print header
1082 ;; 8. Print buffer text (with faces, if specified) and line number
1085 ;; Utilities
1086 ;; ---------
1088 ;; Some tools are provided to help you customize your font setup.
1090 ;; `ps-setup' returns (some part of) the current setup.
1092 ;; To avoid wrapping too many lines, you may want to adjust the
1093 ;; left and right margins and the font size. On UN*X systems, do:
1094 ;; pr -t file | awk '{printf "%3d %s\n", length($0), $0}' | sort -r | head
1095 ;; to determine the longest lines of your file.
1096 ;; Then, the command `ps-line-lengths' will give you the correspondence
1097 ;; between a line length (number of characters) and the maximum font
1098 ;; size which doesn't wrap such a line with the current ps-print setup.
1100 ;; The commands `ps-nb-pages-buffer' and `ps-nb-pages-region' display
1101 ;; the correspondence between a number of pages and the maximum font
1102 ;; size which allow the number of lines of the current buffer or of
1103 ;; its current region to fit in this number of pages.
1105 ;; NOTE: line folding is not taken into account in this process and could
1106 ;; change the results.
1108 ;; The command `ps-print-customize' activates a customization buffer for
1109 ;; ps-print options.
1112 ;; New since version 1.5
1113 ;; ---------------------
1115 ;; Color output capability.
1116 ;; Automatic detection of font attributes (bold, italic).
1117 ;; Configurable headers with page numbers.
1118 ;; Slightly faster.
1119 ;; Support for different paper sizes.
1120 ;; Better conformance to PostScript Document Structure Conventions.

1203 ;; Known bugs and limitations of ps-print
1204 ;; --------------------------------------
1206 ;; Although color printing will work in XEmacs 19.12, it doesn't work
1207 ;; well; in particular, bold or italic fonts don't print in the right
1208 ;; background color.
1210 ;; Invisible properties aren't correctly ignored in XEmacs 19.12.
1212 ;; Automatic font-attribute detection doesn't work well, especially
1213 ;; with hilit19 and older versions of get-create-face. Users having
1214 ;; problems with auto-font detection should use the lists
1215 ;; `ps-italic-faces', `ps-bold-faces' and `ps-underlined-faces' and/or
1216 ;; turn off automatic detection by setting `ps-auto-font-detect' to nil.
1218 ;; Automatic font-attribute detection doesn't work with XEmacs 19.12
1219 ;; in tty mode; use the lists `ps-italic-faces', `ps-bold-faces' and
1220 ;; `ps-underlined-faces' instead.
1222 ;; Still too slow; could use some hand-optimization.
1224 ;; Default background color isn't working.
1226 ;; Faces are always treated as opaque.
1228 ;; Epoch and Emacs 19 not supported. At all.
1230 ;; Fixed-pitch fonts work better for line folding, but are not required.
1232 ;; `ps-nb-pages-buffer' and `ps-nb-pages-region' don't take care
1233 ;; of folding lines.
1236 ;; Things to change
1237 ;; ----------------
1239 ;; Avoid page break inside a paragraph.
1240 ;; Add `ps-non-bold-faces' and `ps-non-italic-faces' (should be easy).
1241 ;; Improve the memory management for big files (hard?).
1242 ;; `ps-nb-pages-buffer' and `ps-nb-pages-region' should take care
1243 ;; of folding lines.
