Description

Linksys PASB421 4-to-1 Bi-Directional Compact Auto Switch ProConnect Parallel

  • Configuration: 4-to-1 or 1-to-4 bi-directional switching
  • Interface: Parallel DB25 Female connectors (5 total ports)
  • Switching Mode: Automatic

  • Form Factor: Compact desktop size
  • Manufactured in Taiwan
  • Unit only; no power adapter or cables included

Applications

This switch was used in office and industrial settings to manage shared parallel printer access across multiple computers, common in legacy DOS, Windows 3.x, 95/98, and early 2000s networked environments. It handles dot-matrix, inkjet, and laser printers with parallel ports. The automatic switching eliminated manual cable swapping in environments where multiple workstations required periodic printer access before network printing became standard.

Condition: Used
This Linksys PASB421 ProConnect Compact Auto Switch is in good used condition. The housing shows some light surface scuffs and general handling wear consistent with prior office use, but there are no cracks or broken parts. All five DB25 parallel ports appear intact, and the DIP switch is present and intact. Please view our photo set and contact us if you have any questions.
