Do you have other devices
running on your computer?
The HP LaserJet 1220 Print•Copy•Scan might not share a
USB or parallel port. If you have a sound card, external hard
drive, or network switchbox connected to the same port as the
HP LaserJet 1220, the other device might be interfering. To
connect and use the HP LaserJet 1220, you must disconnect
the other device or you must use two ports on the computer.
You might need to add another interface card.
Hewlett-Packard strongly recommends an ECP parallel
interface card. See the documentation that came with your
computer for information about installing an additional parallel
interface card or resolving device conflicts.
