Don't waste the parallel port on your inkjet, laser, or high speed
printer. This cable uses the USB port on your PC or hub, so your
parallel port remains free for a zip drive or scanner. Forget the
hassles of IRQ sharing by adapting your 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 bi-directional communication. This
adapter auto-negotiates hardware recognition for faster protocol setup,
and is fully plug-and-play compatible. This cable is fully compliant
with USB 1.1 and IEEE 1284 1994 specifications. It features
bi-directional data transfer at the parallel port to assure high-speed
printing and a maximum data transfer rate of 12 Mbps. It is easy to
install, hot swappable, and does not require any external power adapters
