We have two main network printers at our site, one is a Ricoh, the other a Canon. This week we began experiencing problems printing from computers printing to the Ricoh when connecting through our Exchange server. Our usual solution is to connect directly to the printer via tcp/ip port. Only this time it isn't working. The computer will connect and say the printer is installed, but when a test page (or anything else for that matter) is sent, it just sits in the queue and does nothing. The odd thing about this situation is that the people that were already connected directly to the printer can still print, only those who were connected using our Exchange server are experiencing this problem. Can anyone point me in the right direction here?
