Quick Glance
Key Features
Fast thermal receipt printing
Thermal line printing at a print speed of 250 mm/s keeps the queue moving at a small shop or cafe counter. It prints receipts in black on 79.5 mm or 57.5 mm roll paper, with paper end and paper near-end sensors.
Saves paper on every receipt
The automatic paper reduction function cuts the amount of receipt paper used, an everyday running-cost saving for a busy till. Epson lists the paper saving function as standard on the TM-T20III.
Reliable, with a choice of connection
Epson rates the mechanism life at 15 million lines and the MCBF at 360,000. Choose Ethernet for a networked till, or USB + Serial for a direct connection; the interface is fixed per configuration and is not changeable.
Detailed Specifications
Specifications are Epson's own, from the Epson UAE product pages for the TM-T20III 012 and 011 configurations, which list the same specification; the UK pages list only general rows. Rows Epson's page states without a unit, with conflicting values, or as internal codes (cutter, data buffer, power consumption, dot density, roll diameter and tolerance) are left out.
Need-to-Know
The TM-T20III comes in four configurations. Each is fixed to one interface (Epson lists the interface as not changeable) and one plug region, so choose the one that matches your POS system and power socket.
- Each part number is fixed to one interface - Ethernet, or USB + Serial - and Epson lists the interface as not changeable, so order the configuration that matches your POS system.

- Epson lists two roll paper widths: 79.5 mm and 57.5 mm.
- Epson's UAE page states conflicting cutter information for the TM-T20III, so this page makes no autocutter claim. Ask us if you need a cutter.
- Epson does not publish the printer's weight on its UAE product page.
