What are thermal printer
Thermal printer working principle Thermal printer core parts for the thermal sheet that there is a row of tiny semiconductor element composition . When these elements through a certain current, the semiconductor will produce energy . thermal printer use the thermal paper, the thermal paper coated with a discolored coating, when the discolored coating will be generated a chemical reaction by heat. Since the coating materials of different varieties , so the appearance of colors are black , blue , purple and so on . After the thermal printer receives printing data, the printer will convert the printing data into bitmap Data and then follow point of bitmap data, control the semiconductor element of Printer Mechanism via suitable electric current generate the appropriate temperature. so the print data will be become printing content on thermal paper. Thermal Printer classification Thermal Printer have two type printing methods Thermal Serial Dot
