The key of Portable Receipt Printer technology lies in the heating elements. There is a row of micro semiconductor elements on the core of Thermal Printer Supplies. These elements are arranged very closely, ranging from 200dpi to 600dpi. These elements will generate high temperature quickly when passing a certain current. When the coating of thermal paper meets these elements, the temperature will rise in a very short time, and the coating on thermal paper will undergo chemical reaction Yes, show the color.

After receiving the printing data, the Receipt Printer Manufacturers converts the printing data into bitmap data, and then controls the heating element on the printer core to pass the current according to the point of bitmap data, so that the printing data becomes the printing content on the printing paper.
