I have a GIF12 Card reader & software that connects to a computer via LPT1 port. I want to connect the card reader via a USB port. I need the computer to see the USB port as LPT1.

What you need is a USB to Parallel port adapter. Some adapters have a Centronics 36-pin plug, others have a DB25 plug on the end. Make sure you get one that your card reader will plug into, and make sure it is bi-directional.

You'll need to keep your fingers crossed and hope it will work. If at all possible, I would install a PCI parallel port card in the PC (not possible with laptops, of course).
