more often the not its the cable that is not working, but there are other things you might want to see here. if the printer is not being reconised by the computer then one of these situations may have happend..
1. failed printer controller module (usb port on printer)
2. Bad cable or a cable that is over 3ft in leghts can cause this issue.
3. Software not properly installed or is not comptable with the operating system, Hence windows 7 hates these printers.
please check 1 threw 3 and let me know ether way on your outcome.
