Applications

This device was commonly used in office and industrial environments to share a single parallel printer or peripheral between two computers without unplugging cables. Compatible with legacy parallel port systems including DOS, Windows 95/98, and older Unix workstations. Typical applications included printer sharing on networks before USB became standard, and connecting peripherals like plotters, scanners, and data transfer devices to multiple systems.

Condition: Used
This 25-Pin DB25 2-Way A/B Data Transfer Switch has been inspected and is in good condition. The beige plastic housing shows light surface scuffing consistent with normal storage and handling.
