IOGEAR GUB431 4-Port USB 2.0 Automatic Printer Switch Review

IOGEAR GUB431 4-port USB 2.0 automatic printer switch, USB peripheral sharing switch, share one printer or scanner across 4 computers, no video switching

Not a KVM in the video-switching sense at all: this shares one USB peripheral, typically a printer or scanner, across four computers automatically, without touching video, keyboard, or mouse. It's included here because it lives on the same office peripheral-sharing shelf as small KVMs, not because it switches displays.

Peripheral Sharing, Not Video Switching

This is important to get right: the GUB431 has no video input or output at all. It automatically routes USB traffic from whichever of four computers requests the shared device, most commonly a printer, without any KVM functionality.

Why It's Still Useful Alongside KVMs

Small offices running a KVM switch for their monitor/keyboard/mouse often still need a separate way to share a single printer across machines that aren't all connected to the KVM — this fills that specific gap cheaply.

Comparison to Alternatives

This product isn't a substitute for any KVM switch in this catalog, including IOGEAR's own GCS1794, which handles video/keyboard/mouse/audio but does not include printer-sharing logic. Buyers looking for combined KVM-plus-peripheral sharing across a full console should pair a KVMP switch like the GCS1794 or GCS1924 with this device for printer access specifically, rather than expecting either product to do both jobs alone.
