I just scored an imagewriter II from the local thrift store. It came with a whole bunch of cables and in the box, so I don't think it's broken.
I just can't get it to work. When I try to print something, I get an error message that says that I need to press the "select" button, which I did, but still got the same error message. I have driver software, so I don't think that's the problem either. I am running it on a 7100.
