I have a Win2000 SP3 computer with a HP LJ1200 attached to USB port. Was working fine for a couple of weeks and now it is receiving to "error found..." message when trying to print after a Shutdown or restart. We can get around the error by replugging USB connection, but that is only bubble gum fix. Have connected to rear USB connectors as opposed to the front ones, same problem. Have even replaced USB cable and even tried a different printer, same problem occurs. Everything else on USB ports(mouse, Sprint phone cradle) seems to work fine. Any ideas??
