I have a terminal server 2003 with several printers installed. Users log in to TS and their local or network printer is mapped to the print driver installed on the TS. One of my user's print jobs printed on another users printer. They were not the same print driver. The users cannot see other printers other than their own printer in their session so there was no way for them to have chosen the wrong printer. However, the two users were logged in to the TS at the same time. I'm thinking that somehow both printers mapped to the same TS port, but I do not know how to keep that from happening or what may be causing it. Any suggestions?
