If you are experiencing issues with white dots and white lines on your printed labels, the printer head may has become dirty. In order to resolve this, we recommend cleaning your printer head.
Additionally, using a high-quality thermal label, such as Betckey label paper, can help prevent the poor quality label coating from peeling off and sticking to the print head, ensuring clear printing.
If you have followed these steps and the issue persists, please don't hesitate to contact us for further assistance.
