Using Win2000 Server, Citrix Metaframe Presentation Server 4.0 with hotfix PSE400W2KR01:
A user is able to print from Citrix (using Adobe and Excel) sometimes, and other times, when trying to print the exact same thing a few minutes later, she gets a "you need to install a printer" message from Adobe and a "Current Printer is not available. Select another printer" message from Excel, even though I can see all her auto-created printers on the server in the printer settings. Tried deleting her profile on the server and this did not help.
It seems random as she was able to print earlier to her auto-created printers. Other users on the same application on the same server can print with no problem. There are also network printers installed to the actual Citrix server. Before the PSE400W2KR01 hotfix was installed, she and one other user had this same issue, and it seemed to have been resolved after the hotfix was applied as both were able to print. Now she has the same problem again.
