UNIX driver for hp laserjets?

[Steve Pearse]

Hi, I am looking for a driver for the HP laserjet printers to run on
a 3B20 UNIX V.2 machine. I know about ELAN's "EROFF", but that is $3999.
ARe there any other companies making HP drivers for nroff/troff with
graphics capabilities? Or any vanilla public domain drivers that have
come through the net?

I would appreciate any tips (or better yet, sources for UNIX V.2 drivers)!

Thanks folks,
Steve Pearse
