Sorry, the USB to parallel cable is not as simple as just connecting the wires between the 2 connectors.

You need some electronics in between to convert the serial data from the USB port to parallel data for the parallel port.

I'm not sure if the adapter cables use a single IC, an ASIC, or a combination.

If you have electronics knowledge, you might try searching a couple of IC manufactures sites, or sites like
www.chipcenter.com
for projects to build a protocol adapter.

Okay, if you can't find or order a USB to parallel adapter, you can disable the on-board parallel port in BIOS settings, and install a plug-in card with a parallel port on it.

Just make sure to get a card that has EPP/ECP support.

You might even want to check BIOS settings to see if your on-board port is disabled.
You may be able to repair it by simply enabling the port or changing the port type in BIOS settings.
