Do you print text or graphics (or text in graphics mode via GS)?
Back in the days of that machine, and the ones that claimed to be
compatible, there was a common problem: compression. In a later version
of HP-PCL you can use some compression on bitmaps to reduce the amount
of data that must be transfered via the slow LPT... The symmptome of
"the driver does compression but the printer don't understand it" was
black smear on the left side of the paper, a bit looking like a
histogram. The solution was to disable compression in the driver / use a
driver for an older LJ model.
