The Thermal Printer Has A Clear Feature Of Printing

Thermal printer using thermal printing technology, in the print market has a place, the principle of the key two points: First, thermal paper, the second is high temperature, followed by Xiaobian together to learn more about the principle of thermal printer it ~

Thermal printer, the use of thermal printing technology, that is, the use of special thermal paper, chemical reaction at high temperatures and discoloration, in order to achieve the effect of printing. Thermal Printer In addition to needle printing, thermal printing technology with a small noise, fast, clear print and other characteristics, is now in the banking system, POS terminal systems, medical equipment, Thermal Printer and other aspects of a wide range of applications.

Thermal printer principle - - thermal paper

Thermal paper is a special paper used in thermal printing. It consists of a layer of plain paper and a layer of heat-sensitive coating (mainly containing levure fuel and color reagent), this paper does not occur at room temperature Chemical reaction, in the "latent" state, and at high temperatures, the thermal coating in the hidden color of the fuel and the reaction of a color reaction to produce a certain color, Thermal Printer and the higher the temperature, the faster the color change. So contact with the print head, you can select the desired color change position to print out the required content.

For thermal printers, literally can be understood as the use of sensitive elements in the heating state of the chemical reaction to print the instrument, which will heat the printer to describe the principle of printing most vividly. A print head for heating the thermal paper on the print head of the thermal printer; a print head for selecting a desired print position or image; a thermal paper for receiving a printing position and performing discoloration at a high temperature To achieve the purpose of printing.

Thermal Printer Principle - Comparison

For thermal printers and dot matrix printers are as follows:

Thermal printer: advantages: low noise, fast, easy to print, easy to use;

Disadvantages: can not be double printing, printing paper can not be permanently saved;

Applicable: Suitable for printing documents that do not need to be stored for long periods of time.

Needle printer: Advantages: can be double printing, Thermal Printer printing paper can be permanently saved;

Disadvantages: noise, slow, print writing is not clear, the use of inconvenient;

Applicable to documents that need to be stored for long periods of time.
