What are thermal printer

Thermal printer working principle

Thermal printer core parts for the thermal sheet that there is a row of tiny semiconductor element composition. When these elements through a certain current, the semiconductor will produce energy.

thermal printer use the thermal paper,  the thermal paper coated with a discolored coating, when the discolored coating will be generated a chemical reaction by heat. Since the coating materials of different varieties, so the appearance of colors are black, blue, purple and so on.

After the thermal printer receives printing data, the printer will convert the printing data into bitmap Data and then follow point of bitmap data, control the semiconductor element of Printer Mechanism via suitable electric current generate the appropriate temperature. so the print data will be become printing content on thermal paper.

Thermal Printer classification

Thermal Printer have two type printing methods Thermal Serial Dot System and Thermal Line Dot System. the thermal line is faster than thermal serial methods. HS5801 Thermal Mobile Printer, HS-300 thermal receipt printer, thermal barcode printer XP-233B is thermal line dot system. FD-LTPV445PS、FD-TP211BPS、FD-TP21BP、FD-TP211BS、FD-TP211FPS is thermal serial dot system.

Thermal printer advantages and disadvantages.

Thermal Printer have 3 types: dot matrix. pen plotter, thermal. Compared with the dox matrix printer, thermal printer printing speed is fast, low noise, Legible Image Refinement,

Easy to use Advantage. but the thermal printer unable to printer copies receipt.

the dox matrix printer can print copies receipts. use the best Ribbon, printed the receipt can keep for a long time. but the Dox matrix printer is slow, big noise, Handwriting Rough, need to always change the ribbons. pen plotter printer printing speed is very low, high cost, but it can Paint Vector Graph.
