Application of thermal printer

Thermal printing technology was first used in facsimile machines. Its basic principle is to convert the data received by the printer into dot matrix signals to control the heating of the thermal unit, and heat the thermal coating on the thermal paper to develop. At present, thermal printers have been widely used in POS terminal systems, banking systems, medical instruments and other fields. Thermal printers can only use special thermal paper. The thermal paper is coated with a coating that changes color when exposed to heat, similar to photosensitive film. This characteristic of thermal coatings has brought about thermal printing technology.
