Load 80 mm thermal paper by opening the cover, placing the roll in the compartment, and closing the cover following the paper-path markings.

Use the printer utility or POS software to upload logos or fonts into the internal flash memory if required.

Recommendations

Use high-quality thermal paper rated for receipt printing to maximize print life and clarity. Avoid exposure to direct sunlight and high temperatures to prevent fading. When integrating via RS-232, verify baud rate and handshaking settings to ensure reliable communication. Periodically clean the thermal head with isopropyl alcohol following the manufacturer’s maintenance guidance to maintain print quality.
