Variable: ps-lpr-command
ps-lpr-command is a customizable variable defined in ps-print.el.gz.
Value
"lpr"
Documentation
Name of program for printing a PostScript file.
On MS-DOS and MS-Windows systems, if the value is an empty string then Emacs
will write directly to the printer port named by ps-printer-name. The
programs print and nprint (the standard print programs on Windows NT and
Novell Netware respectively) are handled specially, using ps-printer-name as
the destination for output; any other program is treated like lpr except that
an explicit filename is given as the last argument.
This variable was added, or its default value changed, in Emacs 20.
