I have a data transfer switch which I am trying to hook up to my desk top & lap top so I can share a printer between them. When I hook up the desk top to the printer directly it works fine. when I hook it up throug the data transfer switch I get a message that reads comunication has been lost. and the trouble shooter suggests I check the cable connections. If I switch the box to the other channel I get an "out of paper" message even though I'm not out of paper. Any help would be greatly appreciated.
