Label Printer China technology was first used in fax machines, and its basic principle is to convert the printer received data to the signal control of lattice thermal unit heating, heat sensitive coating on the thermal paper heat enhancement. At present, Label Printer has been widely used in POS terminal system, banking system, medical equipment and other fields.

[edit this paragraph] the key to thermal printing

Label Printer Supplies technology is the key element, thermal printing machine on a row of tiny semiconductor components, these components close together, ranging from 200 dpi to 600 dpi, these components must be in current through is quickly produce high temperature, when the thermal paper coating meet these components, temperature within a very short time increases, the thermal paper coating chemical reaction occurs, color.

Thermal printer, after receiving the POS Receipt Printer data will print data is converted to a bitmap data, then according to the bitmap data point control the heating element on the printing machine through the current, so the print data typed into the print content.
