How does thermal printer print paper stick printer?
Thermal paper surface smooth, is composed of ordinary paper as base paper, coated with a layer of thermosensitive coloring layer above, are painted on the side surface of the ordinary paper, hair layer is composed of adhesive, chromogenic agent, colorless dye (or leuco dye), not through the micro capsule to be separated from the chemical reaction in a latent state. When the heat sensitive paper encounters a heating print head, the printing agent at the place where the printing head prints and the colorless dye produces chemical reaction to change color to form a picture and text
Thermal sensitive paper is a kind of special coated paper, the appearance of which is similar to that of ordinary white paper.
Thermal printer can only use special thermal paper, thermal paper coated with a layer of heat will produce chemical reaction and color coating, similar to the film, but this coating is after the heat discoloration, the characteristic of thermal coating, the thermal printing technology.
