Thermal Printer Introduced

Principle of thermal printer is the print head is provided with a semiconductor heating element, heated print head and when exposed to thermal paper can print out the pattern you want, its principles are similar to thermal fax machines. Image is made by heating up, produced by a chemical reaction in the film. This thermal printer chemical reaction is carried out at a certain temperature. High temperature can accelerate chemical reactions. When the temperature is lower than 60 ℃, paper require considerable, even as long as several years to become dark; and when the temperature 200 ℃, it represents will be completed within a few microseconds.
