The working principle of a thermal printer is to cover a light-colored material with a transparent film, and then heat the film for a period of time to turn it into a dark color.
The image is created by heating, causing a chemical reaction in the film. This chemical reaction takes place at a certain temperature. High temperatures speed up this chemical reaction. When the temperature is less than 60°C, the film takes a very long time, even several years, to turn dark; when the temperature is 200°C, this reaction is completed within a few microseconds.
The thermal printer selectively heats certain locations on the thermal paper, thereby producing corresponding graphics. Heating is provided by a small electronic heater on the print head that is in contact with the heat-sensitive material. The heaters are arranged in the form of square dots or strips and are logically controlled by the printer. When driven, a pattern corresponding to the heating element is produced on the thermal paper.

In daily life, the paper feed speed of a thermal printer is usually used as the evaluation index, that is, the speed is 13mm/s. When the label format is optimized, some printers can print twice as fast. And the thermal printer process is relatively simple, so it can be made into a portable battery-powered thermal label printer. At the same time, thermal printers have flexible printing formats, high image quality, fast speed and low cost. The barcode labels printed by it are not easy to be stored in an environment above 60℃, or exposed to ultraviolet light (such as direct sunlight) for a long time. Time storage. Therefore, thermal barcode labels are usually limited to indoor use.
