+ "*The name of a local printer for printing PostScript files.
+
+On Unix-like systems, a string value should be a name understood by
+lpr's -P option; otherwise the value should be nil.
+
+On MS-DOS and MS-Windows systems, 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 same as `printer-name'; typical non-default
+settings would be \"LPT1\" to \"LPT3\" for parallel printers, or
+\"COM1\" to \"COM4\" or \"AUX\" for serial printers, or
+\"//hostname/printer\" for a shared network printer. 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\".
+
+On DOS/Windows, 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."
