39 ;; Printing Multi-byte Buffer
40 ;; --------------------------
42 ;; The variable `ps-multibyte-buffer' specifies the ps-print multi-byte buffer
45 ;; Valid values for `ps-multibyte-buffer' are:
47 ;; nil This is the value to use the default settings;
48 ;; by default, this only works to print buffers with
49 ;; only ASCII and Latin characters. But this default
50 ;; setting can be changed by setting the variable
51 ;; `ps-mule-font-info-database-default' differently.
52 ;; The initial value of this variable is
53 ;; `ps-mule-font-info-database-latin' (see
56 ;; `non-latin-printer' This is the value to use when you have a japanese
57 ;; or korean PostScript printer and want to print
58 ;; buffer with ASCII, Latin-1, Japanese (JISX0208 and
59 ;; JISX0201-Kana) and Korean characters. At present,
60 ;; it was not tested with the Korean characters
61 ;; printing. If you have a korean PostScript printer,
64 ;; `bdf-font' This is the value to use when you want to print
65 ;; buffer with BDF fonts. BDF fonts include both latin
66 ;; and non-latin fonts. BDF (Bitmap Distribution
67 ;; Format) is a format used for distributing X's font
68 ;; source file. BDF fonts are included in
69 ;; `intlfonts-1.2' which is a collection of X11 fonts
70 ;; for all characters supported by Emacs. In order to
71 ;; use this value, be sure to have installed
72 ;; `intlfonts-1.2' and set the variable
73 ;; `bdf-directory-list' appropriately (see ps-bdf.el
74 ;; for documentation of this variable).
76 ;; `bdf-font-except-latin' This is like `bdf-font' except that it uses
77 ;; PostScript default fonts to print ASCII and Latin-1
78 ;; characters. This is convenient when you want or
79 ;; need to use both latin and non-latin characters on
80 ;; the same buffer. See `ps-font-family',
81 ;; `ps-header-font-family' and `ps-font-info-database'.
83 ;; Any other value is treated as nil.

153 FONT-TYPE is a font type: normal, bold, italic, or bold-italic.
155 FONT-SRC is a font source: builtin, bdf, vflib, or nil.
157 If FONT-SRC is builtin, FONT-NAME is a built-in PostScript font name.

160 alternative font names. To use this font, the external library `ps-bdf'
163 If FONT-SRC is vflib, FONT-NAME is the name of a font that VFlib knows.
164 To use this font, the external library `vflib' is required.
166 If FONT-SRC is nil, a proper ASCII font in the variable
167 `ps-font-info-database' is used. This is useful for Latin-1 characters.
169 ENCODING is a coding system to encode a string of characters of CHARSET into a
170 proper string matching an encoding of the specified font. ENCODING may be a
171 function that does this encoding. In this case, the function is called with
172 one argument, the string to encode, and it should return an encoded string.
174 BYTES specifies how many bytes each character has in the encoded byte
175 sequence; it should be 1 or 2.

178 regardless of a font family of ASCII characters. The exception is Latin-1
