I have one customer trying to print with an HP LaserJet 4250 PCL6. They are on a windows XP machine and running client version 9.23. THe printer is connected by LPT1 and everytime they try to print, the printer goes offline in their session. The strange part is that the local IT person recreated their local windows profile, the printer worked for a few days, and then started doing the same thing again. I have tried re-installing the printer locally as awe as using the HP laserJet 4 driver and the Citrix universal driver in mapping in their session and nothing seems to work. I even re-installed the printer locally using Just the HP laserjEt 4 driver and had the same result. I canot figure out what the issue here is. We have PS 4.5 running on WIN2k3 x64 with all roll-ups current. THey are the only user out of over 2000 experiencing this issue.
