I have a 24" imac and airport express. I wanted to connect my A3 printer to this wireless system. The imac-airport express recognize the epson but the epson refuses to print: I end up with a printing backlog. I get the information that the epson is not on. I thought maybe the problem lay in the usb cable but it works perfectly when connected directly to the imac. Anyone have had a similar problem? Or help with a solution?
