Use this adapter cable to connect your inkjet, laser or high speed printer to a computer without a parallel port. 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. Connector 1: (1) USB-A Male, Connector 2: (1) DB25 Female.
