Many thanks for all the prompt replies. My question regarded the
optimum setup of a HP laserjet 6MP under Solaris 2.6 (see the original
question below).

The solution I used was to set up a separate printer queue for the
windows machines which accepts only 'simple' jobs. Therefore, when it
treats the postscript prepended with printer control as 'simple', it
sends it to the printer rather than attempting to convert it to
postscript again. Thanks to Brooke King and Anthony Worrall for that
suggestion. Other suggestions included telling the windows machine
that the printer was a basic postscript printer (thanks Danny

Thanks also to

Here was my original query:

> I have a Laserjet 6MP connected to the parallel port on my Ultra 30

> The configure script in /etc/lp/printers/laserjet/ is as follows:

> Content types: simple,postscript
> Device: /dev/ecpp0
> Interface: /usr/lib/lp/model/standard
> Printer type: PS

> %-12345X@PJL JOB

> %%Title: Untitled - Notepad

> I've experimented setting the device type with
> lpadmin -p laserjet -T hp
> lpadmin -p laserjet -T hplaser
> lpadmin -p laserjet -T hplaserjet
> but there seems to be no effect.
