Hang on a second -- is the problem that the adapter isn't recognized or that there is no driver for your printer? I have a USB to parallel port adapter that I'm using right now with Vista and it works fine. You might want to try a different adapter. Alternatively, get a network printer server (small box, inexpensive, that plugs into the printer and lets you address the printer as a network device). Then, just use Add a Printer to set up the new printer, DON'T select network printer, use "Local Printer", add a TC/IP port and select that as the port for the printer, and everything will install fine. As an added bonus, you'll be able to access that printer from any other computer on your network.
