ASCXPSE Routine
The ASCXPSE exit routine handles one printer queue to a PostScript-only
printer. This sample exit routine is similar to the LPRXPSE sample
provided for the LPR exits (see LPRXPSE Routine). This exit routine
assumes that the remote printer is PostScript only, or that it will
switch into PostScript mode when it receives a %!PS string
following an EOT (X'04') character.
