Common Mistakes to Avoid

1. Incorrect Label Size Setting in Printer Driver

Reason: The printer driver may be configured for a different label size than the actual labels loaded in the printer, resulting in misaligned or cut-off labels.
Solution: Correct the label size setting in the printer driver to match the physical label dimensions.

2. Using the Wrong Label Type or Media

Reason: Using labels with different dimensions, thickness, or material than what the printer is designed for can lead to printing errors, such as jams or incorrect label placement.
Solution: Ensure that the labels used are compatible with the thermal printer and match the specified size and type.

FAQs

My thermal printer keeps cutting labels at the wrong place, what's wrong?
This usually means the label size settings in your printer driver or software don't match the actual label size you're using. Double-check both the printer settings (looking for options like 'label width' and 'label height') and the specifications on your label roll packaging. Make sure they exactly match. If using software to print, verify the template matches the label size.
