  • Adds a legacy parallel port to modern systems via PCI Express x1 slot
  • Connects printers, programmers and scanners through DB25 interface
  • Runs on Windows, macOS and Linux without jumpers
  • Uses 16C550C-compatible UART with 16-byte FIFO for reliable data transfer
  • Compliant with PCI-Express 1.1 and IEEE 1284 parallel protocol

PCI-E Parallel Port Card

The Barrow Mods adapter adds a single DB25 parallel port through a PCI Express x1 slot. It connects legacy printers, programmers and scanners to modern motherboards. The card fits any PCI Express slot from x1 up to x16 and requires no jumper configuration. A 16C550C compatible UART handles the communication.

Suits legacy hardware owners

Users with parallel printers, CNC controllers or industrial programmers can restore connectivity without USB converters. The card supports Windows from 95 through Server 2008, plus Linux and Mac OS X 10.5. Builders needing multiple parallel ports or USB-based adapters should consider other solutions.

Fits a spare PCIe x1 slot

Installation consumes one PCI Express lane and a rear bracket opening. The board draws power from the slot and assigns I/O address and IRQ automatically via BIOS. No external power cable or driver disk is required for the listed operating systems. The low-profile bracket option suits compact chassis.

Questions about this item

What slot on the motherboard must be free for the PCI-E x1 parallel port card?

A PCI Express x1 slot is required; the card also fits in x4, x8 or x16 slots.

Will the DB25 parallel port work with a legacy printer that only supports SPP mode?

Yes, the card supports SPP, PS2, EPP and ECP modes under the IEEE 1284 protocol.

How can I confirm the card is recognised after installing it in Windows?

Check Device Manager for a new LPT port; the BIOS assigns the I/O address and IRQ automatically.
