We have a few Dataproducts LZR 1260 printers that are shared among a
fairly large user community that uses VAX-class UNIX machines.  Some
users find it convenient to upload Postscript files from their PCs
to the UNIX machines since few people have personal laser printers.
I would also like to upload HP Laser Jet files in the same manner,
however I would need to command the Dataproducts into Laser Jet
emulation mode temporarily.  Knowing nothing of the Postscript lang-
uage, I browsed the Dataproducts manual to see how this could be
accomplished.  If I understand correctly, I must set softwareiomode
to 3 (or 5 - conflicting information in different manual sections).
However, it appears one must know the password to do this and one
risks eventual degradation of an EEPROM if there is frequent toggling
of softwareiomode.  If this is true, it appears that the printer
designers (or Postscript designers?) did not anticipate needs like
mine.  Is there a way to do what I want without knowing the password
or overusing the EEPROM?  If someone has the appropriate Postscript
program available, I'd also appreciate that.
