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’.
