It means that you can blame the user and tell them (or help them) to get a driver upgrade if problem #2 above occurs - which is what I just did a few minutes ago. It's a wonder no other non-vfp problems occurred since the new printer install. All other users had upgraded their drivers to 5Si, and the vfp reports were fine even with the 4Si info.

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.
