>Yeah, most of HP printes family work fine with older drivers, like LaserJet Series II. And I found that if you want to print to file using PostScript driver you have less problems if you use the older ones.

That's been my experience from HP 2/3 & 3/4, but evidently 4 and 5 has some problem working backward. This particular HP5 printer does have some funny internal printer settings and tray setups to accomodate users with odd printing needs, though. I guess the HP4 driver can't handle it...
