  "*Method for printing PostScript files under MS-DOS.

If the value is a string, then it is taken as the name of the
device to which PostScript files are written.  By default it
is the default printer device; typical non-default settings
would be \"LPT1\" to \"LPT3\" for parallel printers, or \"COM1\"
to \"COM4\" or \"AUX\" for serial printers.  You can also set it
to a name of a file, in which case the output gets appended
to that file.  \(Note that `ps-print' package already has
facilities for printing to a file, so you might as well use
them instead of changing the setting of this variable.\)  If
you want to silently discard the printed output, set this to \"NUL\".

If the value is anything but a string, PostScript files will be
piped to the program given by `ps-lpr-command', with switches
given by `ps-lpr-switches', which see."
