The PostScript command:
systemdict begin quit end
resets the LaserWriter when connected to the LaserWriter in PostScript batch
mode via AppleTalk.
This command removes the Laser Prep file, as well as any Postscript program
that has been entered into the LaserWriter. A test page prints after the
command has been executed -- if that option is turned on.
NOTE: To send the previous command, you MUST be in the PostScript batch mode of
the PostScript interactive mode.
The following command can be used in ANY PostScript mode:
serverdict begin 0 exitserver
systemdict begin quit end
