Epson C32C824541 UB-E03 Ethernet CONNECT-IT Interface

The Epson UB-E03 (C32C824541) is a CONNECT-IT modular Ethernet interface card that adds wired network printing capabilities to compatible Epson receipt and POS printers. Rather than relying on an external print server or a direct USB connection to a single workstation, the UB-E03 slots into the printer's dedicated interface bay and connects to the local network via a standard RJ-45 Ethernet cable. It auto-negotiates between 10Base-T and 100Base-TX speeds, ensuring compatibility with the vast majority of wired network infrastructures found in retail, hospitality, and office environments.

Because the UB-E03 is IP addressable, network administrators can assign a static or DHCP-provided IP address and manage the printer remotely, streamlining deployment across multiple locations. The plug-in design eliminates the need for external hardware or additional power sources — the interface draws power directly from the host printer. For businesses that rely on Epson POS printers and need reliable, centralized network printing without the variability of wireless connections, the UB-E03 provides a clean, integrated solution.
