Sabrent USB 2.0 to DB25 IEEE-1284 Parallel Printer Cable Adapter Thumbscrews CB-DB25

SKU CH-W12X-HN4VY

Connects parallel printers to USB ports without drivers, supporting 12 Mbps transfer and IEEE-1284 bi-directional data

  • Connector TypeUSB 2.0
  • Driverless USB-to-parallel conversion for legacy printers
  • Plug-and-play setup with automatic hardware recognition
  • IEEE-1284 and USB 1.1 / 2.0 compliant for broad compatibility
  • Bi-directional parallel data transfer up to 12 Mbps
  • Thumbscrew DB25 connector ensures secure printer attachment

Purpose and audience

This adapter connects a parallel printer with a DB25 port to a USB 2.0 or 1.1 port on a PC or Mac. It targets users who need to keep legacy printers working on modern computers without parallel ports. No driver installation is required for basic operation. Plug and play support simplifies setup across supported Windows and Mac OS versions.

Build and connectors

The cable ends in a USB Type-A plug and a DB25 female connector secured by thumbscrews for a firm, tool-free fit. A six-foot length provides reach between desk and printer. The design draws power from the USB port, so no external supply is needed. Compliance with IEEE 1284 enables bi-directional communication between host and printer.

Interface limits

Maximum throughput is 12 Mbps over the parallel link, bounded by the USB 2.0 and IEEE 1284 specifications. The adapter does not support every printer; some models lack the firmware to accept USB-to-parallel conversion. Windows 98 SE through 8 and Mac OS 9.1 or higher are the listed compatible systems. Newer operating systems may not recognise the device.

Questions about this item

What does the USB 2.0 interface cap the data rate at?

The cable is rated for up to 12 Mbps over the parallel port, limited by the USB 2.0 connection.

What physical connector and mounting style does the parallel end use?

It has a DB25 female connector with thumbscrews to secure it to the printer's DB25 male port.

How is it installed and what step is often missed?

Plug the USB end into the computer and the DB25 end into the printer; the driverless setup is automatic, but verify the printer itself supports USB-to-parallel conversion.
