It’s not that there is port security set up for those devices. I have seen it here with MAC authentication on the ports with printers going off line and you can’t even ping them, it was down to a firmware issue on our HP switches.

It is an autocreated printer. The drivers on the server are either the HP laserJet 4 (if we setup the mapping) or the UPD. In either case it goes offline as soon as we try to print to it. That is offline on the server. I get the feeling that it is an issue with the printer and the fact that it uses the LPT1 port because the user has other printers installed on her PC an they do not have the same issue, but they are either USB or Network printers.

I used to have to go through this process to remove the print drivers completely from Citrix servers in the past and it will be the same on the client, as some .dll file may be corrupted and is hanging round.

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.
