Heat-sensitive Printers Print Fast

- Oct 18, 2017-

The working principle of the heat-sensitive printer is that a semiconductor heating element is installed on the printhead, and the printing head can print out the desired pattern after heating and contacting the heat-sensitive printing paper, which is similar to the heat-sensitive fax machine. Thermal Printer The image is produced by heating the chemical reaction in the membrane. This chemical reaction is carried out at a certain temperature. High temperatures will accelerate this chemical reaction. When the temperature is less than 60 ℃, the paper takes quite a long time, or even a few years to become dark, and when the temperature is 200 ℃, the reaction is done within a few microseconds.

Thermal printer, its heat-sensitive head can be directly installed on the slider, without any other parts involved, the elastic parts can push the pressure of the slider to press the heat-sensitive plates. Thermal Printer One end of the elastic piece is fixed on the slide seat, and the other end is sliding on the reed support seat and its diagonal cutting part. The sliding seat drive shaft of the driving slide seat and the roller drive shaft of the driving paper feed roller are interconnected by a torque transfer mechanism and driven by a single stepper motor. The use of the above structure can reduce parts, cost savings, the use of low-cost small-power motor.

The heat-sensitive printer is selectively heated in the location of the heat-sensitive paper, resulting in a corresponding graphic. Heating is provided by a small electronic heater on a print head that is contacted with a thermosensitive material. The form of the heater row or strip is logically controlled by the printer and, when driven, produces a graph corresponding to the heating element on the heat-sensitive paper. Thermal Printer Control the same logic circuit of the heating element, while also controlling the feed, so that the whole label or paper can be printed on the graph.

The most popular heat-sensitive printer uses a fixed printhead with a heating lattice, with a print head of 320 points, each of which is 0.25mmx0.25mm. Thermal Printer With this dot matrix, the printer can place the print point at any location on the heat-sensitive paper, which has been used on paper printers and label printers.

Application of heat-sensitive printer

Heat-sensitive printing technology was first used in fax machines, the basic principle is to convert the data received by the printer into a lattice of signals to control the heat-sensitive unit heating, heat sensitive paper on the heat-sensitive coating. At present, Thermal Printer thermal printer has been widely used in POS terminal system, banking system, medical equipment and other fields.

Classification of heat-sensitive printers

Thermal printer According to the arrangement of its thermal components can be divided into row-type heat-sensitive (thermal line dot system) and column-type heat-sensitive (thermal Serial dot system). Heat-sensitive column type belongs to the early products, the main application in some of the printing speed is not high, the domestic author in their products used. Line heat sensitive belongs to the the 1990s technology, Thermal Printer its printing speed is much faster than column type heat-sensitive, the fastest speed has reached 220mm/sec at present. To achieve high-speed thermal printing, in addition to the selection of high-speed thermal printing head, there must be a corresponding control board to match.
