CP Technologies CP-UP-05 1.5m Black USB cable

Why waste your parallel port on your high-speed printer? With CP
Tech's USB to IEEE-1284 Printer Cable, you can use your USB port
on your PC or hub and free-up the parallel port for a Zip drive or
scanner. Forget the hassles of IRQ sharing by adapting your high-
speed printer to USB. If you have multiple printers, you can
eliminate the need for a switchbox by connecting each printer to
a USB port. The device is fully transparent to the user, and is
ideal for true bidirectional communication.
