## Long description

Epson TM-T20III (C31CH51011) is a wired direct thermal POS receipt printer designed for small retail and specialty stores, hospitality venues and grocery outlets.

Advantages
The TM-T20III offers a balance of affordability, reliability and performance. Automatic Paper Reduction reduces margins and barcode height to lower paper consumption, while printing the top logo of the next receipt before cutting further reduces top margin.

To minimise paper wear and ensure reliable operation, use thermal paper recommended for Epson POS printers, store spare rolls in a cool dry place, and schedule periodic checks of the cutter and paper path.
