Lines: 62 Keywords: DIABLO 630RO PRINTER I can not get my Diablo 630 RO to print with my A1000. I'm afraid I don't know much about hardware. I have a cable with pins 1-8, 10-13, and 17-25. The pins don't switch around. i.e. pin 1 at one end goes to pin 1 on the other end. How do I rewire this cable so I can print? Using this cable I can not even get garbage from the printer.
