Product information

Description

The Epson TM-T20III (011) is a wired direct-thermal POS receipt printer designed for small retail, specialty stores, hospitality venues and grocery stores. It supports 80 mm paper width, offers a print resolution up to 203 x 203 dpi and provides reliable operation with a mean time between failures (MTBF) of 360,000 hours and a cutter life rated for 1.5 million cuts. The printer is available in black and comes in configurations with USB + Serial or Ethernet connectivity.

Advantages

The TM-T20III combines an economical design with practical features that reduce paper usage and operating costs. Automatic Paper Reduction lowers top and bottom margins, line feed width and barcode height, and the printer can print the top logo of the next receipt before cutting to reduce the top margin by an additional 12 mm. With a mechanism life rated for 15 million lines and a print speed up to 250 mm/s, the model is suitable for continuous, high-volume retail printing while maintaining low noise levels.

How to use

Connect the Epson TM-T20III to a POS terminal using the provided USB or serial cable, or install the Ethernet model where network connectivity is required. Load an 80 mm thermal paper roll into the printer following the feed path indicated inside the cover. Configure the POS software to recognise the TM-T20III and select appropriate paper settings and character encoding. Use the printer’s reduction features and logo printing option to optimise paper usage where supported by the POS software.

Usage recommendations

Use certified thermal receipt paper of the correct 80 mm width and do not exceed the recommended maximum roll diameter. Perform periodic cleaning of the print head and cutter as described in the user manual to maintain print quality and extend mechanism life. Choose the connectivity model that matches your POS setup; the USB + Serial model supports legacy systems while an Ethernet model can be adopted for networked environments.
