-;;
-;; 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.

+;;
+;; 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.
