The Thermal Printer Has A Clear Feature Of Printing

- Oct 27, 2017-

The thermal printer works by installing a semiconductor heating element on the printhead. The print head is heated and touched with the thermal paper to print out the desired pattern. The principle is similar to that of a thermal printer. The image is generated by heating and producing a chemical reaction in the membrane. This chemical reaction is carried out at a certain temperature. High temperature will accelerate this chemical reaction. Thermal Printer When the temperature is below 60 ℃, the paper needs to go through a long, or even several years to become dark; and when the temperature is 200 ℃, this reflection will be completed in a few microseconds.

The thermal printer selectively heats the determined position of the thermal paper, thereby producing a corresponding pattern. The heating is provided by a small electronic heater on the printhead in contact with the thermosensitive material. The heater is arranged in the form of a square or strip in the form of a logic control by the printer, and when driven, a pattern corresponding to the heating element is produced on the thermal paper. Thermal Printer Control the heating logic of the same logic circuit, but also control the feed, which can be printed on the entire label or paper graphics.

 The most popular thermal printer uses a fixed printhead with a heated lattice, Thermal Printer with a print head with 320 square points, each 0.25mm × 0.25mm. With this dot matrix, the printer can print at any point on the thermal paper, which has been used on paper printers and label printers.

The application of thermal printer

Thermal printing technology used in the first fax machine, the basic principle is to receive the data received by the printer into a lattice signal to control the heating of the thermal unit, Thermal Printer the thermal paper thermal coating heated development. At present, the thermal printer has been widely used in POS terminal systems, banking systems, medical equipment and other fields.

 Classification of thermal printers

 Thermal printer can be divided into thermal line Dot System and Thermal Serial Dot System according to the arrangement of thermal elements. Column type heat is an early product, Thermal Printer the main application in some of the printing speed is not demanding on the occasion, the domestic author has used in its products. Line heat is the 20th century, 90 years of technology, Thermal Printer the print speed is much faster than the type of heat, the fastest speed has reached 220mm / s. To achieve high-speed thermal printing, in addition to select high-speed thermal print head, but also must have a corresponding control panel with.

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