Usage recommendations

For best results, use direct-thermal label stock within the specified width (30–118 mm) and thickness (0.06–0.22 mm), keep the print head and sensors clean, and calibrate media settings after loading new label types. Avoid prolonged exposure of printed labels to heat or sunlight to preserve readability.
