In fact, it has many personalities, PS is one of them. It also
handles PCL, and additionally ASCII. Therefore it has a multiple
personality disorder, but that's actually fine, because each of
them has its advantage.
Personalities can be selected at the operator panel of the printer.
Setting AUTO usually causes the correct output to appear.

I found that using PS directly is slower than using gs, but I'm
going with this solution with just works (TM) for many years now.
The reason might be that I also had other printers in the same
location (HP Laserjet 4, Lexmark Optra something, Kyocera FS-600)
which all understand the gs-generated data without me having to
change anything. That's a very lazy man's solution, I know. :-)
Currently I'm using CUPS with a PPD file, so I think things are
kept in PS the whole way (PPD used to modify PS).
