The working principle of thermal printer is equipped with POS Printer USAhead semiconductor heating elements, the POS Printer Kenyahead heat and contact thermal printing paper can print out the need to design, the principle is similar to thermal fax machines. The image is created by heating and producing a chemical reaction in the membrane. This chemical reaction takes place at a certain temperature. High temperature will accelerate this chemical reaction. When the temperature is lower than 60 ℃, the paper takes quite long, even for a few years time to become dark; When temperature is 200 ℃, this will be done within a few microseconds.

Ios Printer Supplier: The thermal printer selectively heats the thermal sensitive paper at a certain position, resulting in the corresponding graph. The heating is provided by a small electric heater on the print head in contact with the heat sensitive material. The heater is logically controlled by the printer in the form of a square point or strip. When driven, a graph corresponding to the heating element is generated on the thermal sensitive paper. The same logic circuit that controls the element of heating, and also controls the entry of the paper, so that graphics can be printed on the entire label or paper.

The most common Ios Printer USES a fixed print head with a heating array of 320 square points, each of which is 0.25mm x 0.25mm. Using this matrix, the printer can place the print point anywhere on the thermal sensitive paper. This technology has been used on paper printers and label printers.
