33;;
34;; This package is used for ps-print to print multi-byte buffer.

39;; Printing Multi-byte Buffer
40;; --------------------------
41;;
42;; The variable `ps-multibyte-buffer' specifies the ps-print multi-byte buffer
43;; handling.
44;;
45;; Valid values for `ps-multibyte-buffer' are:
46;;
41a247c2
VJL
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
c276ee05
KH
51;; `ps-mule-font-info-database-default' differently.
52;; The initial value of this variable is
53;; `ps-mule-font-info-database-latin' (see
54;; documentation).
2cb842ae 55;;
41a247c2 56;; `non-latin-printer' This is the value to use when you have a japanese
2cb842ae
KH
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,
41a247c2
VJL
60;; it was not tested with the Korean characters
61;; printing. If you have a korean PostScript printer,
62;; please, test it.

41a247c2 64;; `bdf-font' This is the value to use when you want to print
2cb842ae

65;; buffer with BDF fonts. BDF fonts include both latin
66;; and non-latin fonts. BDF (Bitmap Distribution

2cb842ae
KH
73;; `bdf-directory-list' appropriately (see ps-bdf.el
74;; for documentation of this variable).
75;;
41a247c2 76;; `bdf-font-except-latin' This is like `bdf-font' except that it uses
2cb842ae
KH
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'.
82;;
83;; Any other value is treated as nil.
84;;
85;; The default is nil.
