C2G 1.8M USB-A Male to DB25 Female Parallel Printer Adapter Cable Use this adapter cable to connect your inkjet, laser or high speed printer to a computer without a parallel port, or free up the parallel port 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. Note: This adapter is designed for use with a standard Parallel printer and is not designed to support multi-function printers or other parallel devices. This adapter uses the USB Printing Support function of the operating system and is not designed to create a LPT port.

User manual DB25 A DB25 connector has 25 pins arranged in two rows, with one row on top of the other. The top row has 13 pins and the lower row has 12 pins. DB25 connectors are most often used for parallel, RS-232 serial, or SCSI applications. An older PC would normally have one DB25 female parallel port. In Parallel applications, the DB25 connector is sometimes referred to as the IEEE-1284 Type A connector. On older PCs, a male DB25 serial port could sometimes be found instead of a DB9. DB25 SCSI connections are female, and can be found on older Apple computers as well as on expansion cards for SCSI peripheral devices. USB-A Found on host controllers in computers and hubs, the A-style connector is a flat, rectangular interface. This interface holds the connection in place by friction which makes it very easy for users to connect and disconnect. Instead of round pins, the connector uses flat contacts which can withstand continuous attachment and removal very well. The A-socket connector provides a "downstream" connection that is intended for use solely on host controllers and hubs. It was not intended for use as an "upstream" connector on a peripheral device. This is critical because a host controller or hub is designed to provide 5V DC power on one of the USB pins.
