How do I simulate a parallel (LPT) Printer with a USB Printer?

I have a legacy DOS application that needs to print to a LPT port and only have USB ports on the host machine. I have installed a usb to parallel adapter to connect the printer. The adapter installed correctly with the USB Printer Support driver, however the adapter does not appear as a LPT port.

How do I assign a LPT port to the usb adapter?

I would suspect you need to review the software it came with, or visit the manufacturers site. What is the adapter you used? –  Dave Jan 2 '13 at 13:09
    
i am using the prolific usb to parallel adapter. I have used this adapter before and was able to go to the device properties and assign a lpt port. Now, for some reason I can't, the device only appear as a usb port. –  Hendre Jan 2 '13 at 17:33
