Ever since we added an HPLJ4250n (possibly related or not) to one of our remote locations (that Terminal Server's into our network for Microsoft Great Plains) we been having issues with (some) user sessions freezing up - usually right after someone starts printing something. At first we were seeing something to do with the power meter not responding; but have since uninstalled APC's Powerchute software and don't seem to be seeing that error anymore. I've found from this link:
that stopping and starting the printer spool service on this TS box fixes the problem most of the time - sometimes I'll still have to manually log off one or two users. But I would like to resolve this problem properly, right now we're having these freeze ups about 3 times a week and its a PITA. I've tried changing the HP driver but that didn't seem to make any difference. Does anyone have any ideas / suggestions on what else I could try?
