41 ;; Printing Multi-byte Buffer
42 ;; --------------------------
44 ;; The variable `ps-multibyte-buffer' specifies the ps-print multi-byte buffer
47 ;; Valid values for `ps-multibyte-buffer' are:
49 ;; nil This is the value to use the default settings which
50 ;; is by default for printing buffer with only ASCII
51 ;; and Latin characters. The default setting can be
52 ;; changed by setting the variable
53 ;; `ps-mule-font-info-database-default' differently.
54 ;; The initial value of this variable is
55 ;; `ps-mule-font-info-database-latin' (see
58 ;; `non-latin-printer' This is the value to use when you have a japanese
59 ;; or korean PostScript printer and want to print
60 ;; buffer with ASCII, Latin-1, Japanese (JISX0208 and
61 ;; JISX0201-Kana) and Korean characters. At present,
62 ;; it was not tested the Korean characters printing.
63 ;; If you have a korean PostScript printer, please,
66 ;; `bdf-font' This is the value to use when you want to print
67 ;; buffer with BDF fonts. BDF fonts include both latin
68 ;; and non-latin fonts. BDF (Bitmap Distribution

74 ;; `intlfonts-1.1' and set the variable
75 ;; `bdf-directory-list' appropriately (see ps-bdf.el
76 ;; for documentation of this variable).
78 ;; `bdf-font-except-latin' This is like `bdf-font' except that it is used
79 ;; PostScript default fonts to print ASCII and Latin-1
80 ;; characters. This is convenient when you want or
81 ;; need to use both latin and non-latin characters on
82 ;; the same buffer. See `ps-font-family',
