 The principle of thermal printer is that a layer of hyaloid membrane is added to the light material (usually paper) to heat the film for a period of time.

It turns dark (usually black, but also blue). The image is heated to produce biochemical response in the film.

Generated. This chemical reaction is carried out at a certain temperature. High temperature will accelerate this chemical reaction. When the temperature

when it is lower than 60 ℃, the film needs to go through a long time, even for several years to become dark; And when the temperature is

at 200℃, this reflection will be completed within a few microseconds.

  The thermal printer selectively heats at a certain position of thermosensitive paper, thus generating corresponding graphics. Heating

it is provided by a small electronic heater on the print head in contact with the heat-sensitive material. The heater is arranged into square points or bars.

The form is logically controlled by the printer. When driven, a heating element is generated on the thermosensitive paper.

Graphics. The same logic circuit that controls the heating element and also controls the paper feed, so it can be used on the entire label or paper.

A graphic is printed on it. The most common thermal printer uses a fixed print head with heating dot matrix, and the print head is equipped

320 square points, each point is 0.25mm × 0.25mm. With this dot matrix, the printer can put the printing point on the hot

any position of the sensitive paper. This technology has been used in paper printers and label printers.
