Epson C32C823991*SI USB Interface Board for T88IV
Overview
The Epson C32C823991*SI is a USB interface board designed for direct integration into Epson T88IV thermal receipt printers. This component provides onboard USB connectivity, enabling hardwired communication between the printer and host systems — eliminating serial or parallel cable dependencies in point-of-sale, logistics, and warehouse environments. Install this board during initial T88IV configuration or as a retrofit when upgrading existing deployments to USB-native infrastructure.
Compatibility
The C32C823991*SI is engineered specifically for Epson T88IV and compatible TM-series thermal printers. Verify your printer model supports onboard interface module retrofit before ordering. Integration occurs at the printer's motherboard — motherboard slot requirements and firmware compatibility depend on your specific T88IV revision and regional thermal printer configuration.
Installation Notes
This is an internal component requiring motherboard-level installation. Deployment requires basic electronics assembly skills or qualified integrator support. No external power or cabling is needed — the board draws power directly from the printer's internal supply. Ensure the printer is powered down and disconnected before installation. Consult the T88IV service manual for motherboard access and slot orientation. After installation, verify USB enumeration in the host operating system before production use.
