Label Paper

It is recommended to use official, genuine consumables from NIIMBOT for consistent high-quality printing results. Specially designed label products can enhance the printer’s performance and prevent premature wear and tear of the print head.

01.Confirming Label Material 1 For regular thermal label paper, you can use your fingernail or a pen cap to
scratch the printing surface. 2 NIIMBOT’s official, genuine thermal label paper enhances durability and
water resistance; it requires a lighter or heat source for baking. 3 Check if there are black marks on the label paper.
1. If black markings appear on the medium, the label material is thermal sensitive, which this printer supports.
2. If black markings do not appear on the medium, the label material is thermal transfer, and it requires the use of a ribbon. This printer does not support this type.
