The cable is 6 feet long. 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.
