34 | ;; About ps-mule | |
35 | ;; ------------- | |
36 | ;; | |
37 | ;; This package is used for ps-print to print multi-byte buffer. | |
38 | ;; | |
39 | ;; See also ps-print.el. | |
40 | ;; | |
41 | ;; | |
42 | ;; Printing Multi-byte Buffer | |
43 | ;; -------------------------- | |
44 | ;; | |
45 | ;; The variable `ps-multibyte-buffer' specifies the ps-print multi-byte buffer | |
46 | ;; handling. | |
47 | ;; | |
48 | ;; Valid values for `ps-multibyte-buffer' are: | |
49 | ;; | |
c276ee05 KH |
50 | ;; nil This is the value to use the default settings which |
51 | ;; is by default for printing buffer with only ASCII | |
52 | ;; and Latin characters. The default setting can be | |
53 | ;; changed by setting the variable | |
54 | ;; `ps-mule-font-info-database-default' differently. | |
55 | ;; The initial value of this variable is | |
56 | ;; `ps-mule-font-info-database-latin' (see | |
57 | ;; documentation). | |
2cb842ae KH |
58 | ;; |
59 | ;; `non-latin-printer' This is the value to use when you have a japanese | |
60 | ;; or korean PostScript printer and want to print | |
61 | ;; buffer with ASCII, Latin-1, Japanese (JISX0208 and | |
62 | ;; JISX0201-Kana) and Korean characters. At present, | |
63 | ;; it was not tested the Korean characters printing. | |
64 | ;; If you have a korean PostScript printer, please, | |
65 | ;; test it. | |
66 | ;; | |
67 | ;; `bdf-font' This is the value to use when you want to print | |
68 | ;; buffer with BDF fonts. BDF fonts include both latin | |
69 | ;; and non-latin fonts. BDF (Bitmap Distribution | |
70 | ;; Format) is a format used for distributing X's font | |
71 | ;; source file. BDF fonts are included in | |
922be019 | 72 | ;; `intlfonts-1.2' which is a collection of X11 fonts |
2cb842ae KH |
73 | ;; for all characters supported by Emacs. In order to |
74 | ;; use this value, be sure to have installed | |
922be019 | 75 | ;; `intlfonts-1.2' and set the variable |
2cb842ae KH |
76 | ;; `bdf-directory-list' appropriately (see ps-bdf.el |
77 | ;; for documentation of this variable). | |
78 | ;; | |
79 | ;; `bdf-font-except-latin' This is like `bdf-font' except that it is used | |
80 | ;; PostScript default fonts to print ASCII and Latin-1 | |
81 | ;; characters. This is convenient when you want or | |
82 | ;; need to use both latin and non-latin characters on | |
83 | ;; the same buffer. See `ps-font-family', | |
84 | ;; `ps-header-font-family' and `ps-font-info-database'. | |
85 | ;; | |
86 | ;; Any other value is treated as nil. | |
87 | ;; | |
88 | ;; The default is nil. | |
