40 ;; Printing Multi-byte Buffer
41 ;; --------------------------
43 ;; The variable `ps-multibyte-buffer' specifies the ps-print multi-byte buffer
46 ;; Valid values for `ps-multibyte-buffer' are:
48 ;; nil This is the value to use the default settings;
49 ;; by default, this only works to print buffers with
50 ;; only ASCII and Latin characters. But this default
51 ;; setting can be changed by setting the variable
52 ;; `ps-mule-font-info-database-default' differently.
53 ;; The initial value of this variable is
54 ;; `ps-mule-font-info-database-latin' (see
57 ;; `non-latin-printer' This is the value to use when you have a japanese
58 ;; or korean PostScript printer and want to print
59 ;; buffer with ASCII, Latin-1, Japanese (JISX0208 and
60 ;; JISX0201-Kana) and Korean characters. At present,
61 ;; it was not tested with the Korean characters
62 ;; printing. If you have a korean PostScript printer,
65 ;; `bdf-font' This is the value to use when you want to print
66 ;; buffer with BDF fonts. BDF fonts include both latin
67 ;; and non-latin fonts. BDF (Bitmap Distribution
68 ;; Format) is a format used for distributing X's font
69 ;; source file. BDF fonts are included in
70 ;; `intlfonts-1.2' which is a collection of X11 fonts
71 ;; for all characters supported by Emacs. In order to
72 ;; use this value, be sure to have installed
73 ;; `intlfonts-1.2' and set the variable
74 ;; `bdf-directory-list' appropriately (see ps-bdf.el
75 ;; for documentation of this variable).
77 ;; `bdf-font-except-latin' This is like `bdf-font' except that it uses
78 ;; PostScript default fonts to print ASCII and Latin-1
79 ;; characters. This is convenient when you want or
80 ;; need to use both latin and non-latin characters on
81 ;; the same buffer. See `ps-font-family',
82 ;; `ps-header-font-family' and `ps-font-info-database'.
84 ;; Any other value is treated as nil.

156 FONT-SRC is a font source: builtin, bdf, vflib, or nil.

164 If FONT-SRC is vflib, FONT-NAME is the name of a font that VFlib knows.
165 To use this font, the external library `vflib' is required.
167 If FONT-SRC is nil, a proper ASCII font in the variable
168 `ps-font-info-database' is used. This is useful for Latin-1 characters.

171 proper string matching an encoding of the specified font. ENCODING may be a
172 function that does this encoding. In this case, the function is called with
173 one argument, the string to encode, and it should return an encoded string.
175 BYTES specifies how many bytes each character has in the encoded byte
176 sequence; it should be 1 or 2.
