The machine does have a parallel port.... its a mini-parallel port. Its not the standard old-school type parallel port. You will need that cable to perform this firmware upgrade/repair.

The error message you have is a firmware error. Either the wrong firmware file was sent to the machine or the firmware file is corrupted on the engine. Firmware on a HP engine usually gets performed via the parallel port (even though it may have a NIC or USB).

I'd remove any options fitted to the machine, such as extra trays, duplex units or output trays, the resend the correct firmware file to the machine. Full details on this are usually on the HP website. Its quite straight-forward.
