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. You can turn off color processing by setting
ps-print-color-p
to nil
.
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.
Many other customization variables for these commands are defined and described in the Lisp file `ps-print.el'.
