Overview

The Epson C32C824541 UB-E03 Print Server is a plug-in module designed to bring Ethernet connectivity to compatible Epson TM series printers. Rather than tethering a receipt or label printer to a single workstation via USB or serial cable, the UB-E03 lets you place the printer on your local network, making it accessible from multiple computers and POS terminals. This is especially valuable in retail, hospitality, and warehouse environments where shared printing streamlines operations.

Supporting both 10Base-T and 100Base-TX Ethernet standards, the module provides reliable connectivity across a variety of network setups. Installation is straightforward — the module slides into the UB-type interface bay found on compatible Epson TM printers such as the TM-C3400E and TM-L90LF, requiring nothing more than an Ethernet cable to get up and running. Its compact form factor integrates seamlessly with the printer, keeping your workspace clean and uncluttered.
