How does a thermal printer work? Choosing the right paper
Choose with confidence
From the explanation to the appropriate role.
Always check the type of paper and material on the specific article. Through these selection paths you get to roller dimensions, packs and device instructions.

In direct thermal printing, the print head selectively heats the heat-sensitive coating of thermal paper. This creates the printed image without an ink cartridge or ribbon. This process is used for till receipts and payment terminal receipts, for example.
Thermal transfer is a different process: a heated print head transfers ink from a ribbon onto the print medium. Printers described as thermal printers therefore do not all use the same type of paper.
When choosing rolls, first check the printing process in the device documentation, then the width, maximum outer diameter and core opening. Plain paper cannot replace thermal paper in a direct thermal printer.
Heat, light and storage conditions can affect thermal paper. Follow the paper manufacturer’s storage instructions. The term “thermal paper” alone does not imply any particular archival life.
