How to use

Install the TM-T20IV on a stable surface near the POS terminal and connect it using the appropriate cable (USB and serial; connect Ethernet if the model supports LAN). Load 80 mm thermal paper rolls with the thermal side facing the print head and ensure the roll diameter does not exceed 83 mm. After powering on, install the provided or latest Epson drivers on the connected POS system, configure paper size and interface settings in the POS software, and run a test print to confirm correct operation. Monitor the status LED for error or paper notifications and replace the paper roll as needed.

Recommendations

Use high-quality 80 mm thermal paper designed for receipt printing to ensure print longevity and reduce paper jams. Place the printer in a dry, dust-free location and avoid direct sunlight to preserve the print head. For high-volume environments enable paper-saving modes in the POS software when available, and consider an extended service plan for continuous coverage beyond the standard 2-year warranty.
