Variables for PostScript Hardcopy
=================================

   All the PostScript hardcopy commands use the variables
`ps-lpr-command' and `ps-lpr-switches' to specify how to print the
output.  `ps-lpr-command' specifies the command name to run,
`ps-lpr-switches' specifies command line options to use, and
`ps-printer-name' specifies the printer.  If you don't set the first
two variables yourself, they take their initial values from
`lpr-command' and `lpr-switches'.  If `ps-printer-name' is `nil',
`printer-name' is used.

   The variable `ps-print-header' controls whether these commands add
header lines to each page--set it to `nil' to turn headers off.

   If your printer doesn't support colors, you should turn off color
processing by setting `ps-print-color-p' to `nil'.  By default, if the
display supports colors, Emacs produces hardcopy output with color
information; on black-and-white printers, colors are emulated with
shades of gray.  This might produce illegible output, even if your
screen colors only use shades of gray.

   By default, PostScript printing ignores the background colors of the
faces, unless the variable `ps-use-face-background' is non-`nil'.  This
is to avoid unwanted interference with the zebra stripes and background
image/text.

   The variable `ps-paper-type' specifies which size of paper to format
for; legitimate values include `a4', `a3', `a4small', `b4', `b5',
`executive', `ledger', `legal', `letter', `letter-small', `statement',
`tabloid'.  The default is `letter'.  You can define additional paper
sizes by changing the variable `ps-page-dimensions-database'.

   The variable `ps-landscape-mode' specifies the orientation of
printing on the page.  The default is `nil', which stands for
"portrait" mode.  Any non-`nil' value specifies "landscape" mode.

   The variable `ps-number-of-columns' specifies the number of columns;
it takes effect in both landscape and portrait mode.  The default is 1.

   The variable `ps-font-family' specifies which font family to use for
printing ordinary text.  Legitimate values include `Courier',
`Helvetica', `NewCenturySchlbk', `Palatino' and `Times'.  The variable
`ps-font-size' specifies the size of the font for ordinary text.  It
defaults to 8.5 points.

   Emacs supports more scripts and characters than a typical PostScript
printer.  Thus, some of the characters in your buffer might not be
printable using the fonts built into your printer.  You can augment the
fonts supplied with the printer with those from the GNU Intlfonts
package, or you can instruct Emacs to use Intlfonts exclusively.  The
variable `ps-multibyte-buffer' controls this: the default value, `nil',
is appropriate for printing ASCII and Latin-1 characters; a value of
`non-latin-printer' is for printers which have the fonts for ASCII,
Latin-1, Japanese, and Korean characters built into them.  A value of
`bdf-font' arranges for the BDF fonts from the Intlfonts package to be
used for _all_ characters.  Finally, a value of `bdf-font-except-latin'
instructs the printer to use built-in fonts for ASCII and Latin-1
characters, and Intlfonts BDF fonts for the rest.

   To be able to use the BDF fonts, Emacs needs to know where to find
them.  The variable `bdf-directory-list' holds the list of directories
where Emacs should look for the fonts; the default value includes a
single directory `/usr/local/share/emacs/fonts/bdf'.

   Many other customization variables for these commands are defined and
described in the Lisp files `ps-print.el' and `ps-mule.el'.
