+ ;; -------------
+ ;;
+ ;; This package is used for ps-print to print multi-byte buffer.
+ ;;
+ ;; See also ps-print.el.

+ ;;
+ ;; Printing Multi-byte Buffer
+ ;; --------------------------
+ ;;
+ ;; The variable `ps-multibyte-buffer' specifies the ps-print multi-byte buffer
+ ;; handling.
+ ;;
+ ;; Valid values for `ps-multibyte-buffer' are:
+ ;;
+ ;; nil This is the value to use the default settings
which
+ ;; is by default for printing buffer with only ASCII
+ ;; and Latin characters. The default setting can be
+ ;; changed by setting the variable
+ ;; `ps-mule-font-info-database-default' differently.
+ ;; The initial value of this variable is
+ ;; `ps-mule-font-info-database-latin' (see
+ ;; documentation).
+ ;;
+ ;; `non-latin-printer' This is the value to use when you have a japanese
+ ;; or korean PostScript printer and want to print
+ ;; buffer with ASCII, Latin-1, Japanese (JISX0208 and
+ ;; JISX0201-Kana) and Korean characters. At present,
+ ;; it was not tested the Korean characters printing.
+ ;; If you have a korean PostScript printer, please,
+ ;; test it.
+ ;;
+ ;; `bdf-font' This is the value to use when you want to print
+ ;; buffer with BDF fonts. BDF fonts include both latin
+ ;; and non-latin fonts. BDF (Bitmap Distribution
+ ;; Format) is a format used for distributing X's font
+ ;; source file. BDF fonts are included in
+ ;; `intlfonts-1.2' which is a collection of X11 fonts
+ ;; for all characters supported by Emacs. In order to
+ ;; use this value, be sure to have installed
+ ;; `intlfonts-1.2' and set the variable
+ ;; `bdf-directory-list' appropriately (see ps-bdf.el
+ ;; for documentation of this variable).
+ ;;
+ ;; `bdf-font-except-latin' This is like `bdf-font' except that it is used
+ ;; PostScript default fonts to print ASCII and Latin-1
+ ;; characters. This is convenient when you want or
+ ;; need to use both latin and non-latin characters on
+ ;; the same buffer. See `ps-font-family',
+ ;; `ps-header-font-family' and `ps-font-info-database'.
+ ;;
+ ;; Any other value is treated as nil.
+ ;;
+ ;; The default is nil.

+ (FONT-SRC FEATURE INITIALIZED-P
+ PROLOGUE-FUNC CHECK-FUNC FONT-FUNC GLYPH-FUNC)
+
+ FONT-SRC is the font source: builtin, bdf, pcf, or vflib.
+
+ FEATURE is the feature that provide a facility to handle FONT-SRC. Except for
+ `builtin' FONT-SRC, this feature is automatically `require'd before handling
+ FONT-SRC. Currently, we only have the feature `ps-bdf'.
+
+ INITIALIZED-P indicates if this library is initialized or not.
+
+ PROLOGUE-FUNC is a function to generate PostScript code which
+ define several PostScript procedures that will be called by
+ FONT-FUNC and GLYPHS-FUNC. It is called with no argument, and
+ should return a list of strings.
+
+ CHECK-FUNC is a function to check if a font is available or not.
+ It is called with one argument FONT-SPEC, and should return
+ non-nil iff the font specified in FONT-SPEC is available.
+
+ FONT-FUNC is a function to generate PostScript code which define
+ a new font. It is called with one argument FONT-SPEC, and should
+ return a list of strings.
+
+ GLYPH-FUNC is a function to generate PostScript code which define a glyph of
+ characters. It is called with two arguments FONT-SPEC and CODE,
+ and should return a list of strings.")
