How to Connect a USB Printer to an LPT Port

By Brian Cleary

Although less used today, you may encounter an LPT, or parallel, port on an older computer in your office. Because newer printers -- as well as most other peripherals -- are USB devices, you need a special adapter in order to plug your printer's USB cable into the older computer's LPT port. You can purchase this adapter online or at most computer supply stores.

Install the printer software that came with your printer on the computer with the LPT port. This CD includes important drivers and software that the computer needs in order to be able to communicate with the printer. When complete, shut down the computer.

Plug the USB connector from your printer into the LPT/USB adapter, and then plug the adapter into the LPT port on the computer.

Power on the printer first, followed by the computer. Windows identifies the new hardware that's connected to the computer, and you can begin using the printer with the computer.

Items you will need

  • USB to LPT port adapter

  • Printer software CD


The parallel port to USB adapter works both ways as long as one side of the connection has a USB port and the other has a parallel port.
