Install the manufacturer drivers or standard POS printer drivers on your system and test-print a sample label to verify alignment and print quality.

Recommendations

Use the specified media thickness range (0.06–0.2 µm) and keep the print head clean to maintain print quality and prolong the life of the device. Select thermal transfer mode with compatible ribbons for long-lasting labels, and ensure the real-time clock is set correctly when timestamps are required.
