Label printer type

Average person is usually a needle know LCD Module Manufacturer, inkjet and laser printing, but you may not have noticed that, in our surrounding environment, almost all goods have printed label by using thermal transfer technology, for example, open the following from, KIOSK Receipt Printer Driver, inside can see thickly dotted with barcode label, generally the advanced packaging wheat head has with thermal transfer printing out a product label stickers, also usually with barcode. In additional, when buying clothing, clothing tags also usually have Small LCD Module, thermal transfer printing way in the railway station to buy train ticket, boarding pass and baggage tag, etc., are also using thermal transfer printing technology, especially behind almost all electrical products, have some thermal transfer technology is used to print the marking label, like a laptop is more than a way of of all kinds in this print to Mini Thermal Printer.

Label printer experienced the keyboard era and the era of intelligence, touch screen era

In the earliest label printer is the keyboard era, now into an era where everything is intelligent, label printers can not lag behind. So the intelligent label printer comes into being, let us enter the intelligent era of label printer. Label printers include keyboard-type label printers, touch-screen label printers, and smart portable label printers for app operating versions.

About heat sensitive paper

WIFI POS Printer machine currently USES thermal printers. The following are the relevant materials of thermal printers. I hope you can understand this knowledge.

Thermal printer can only use a dedicated thermal paper, thermal paper coated with a layer of will react when it is heated and the coating color, similar to the film, but this will change color after coating is heated, the use of the properties of thermosensitive coating, thermal printing technology came into being.

WIFI POS Printer Wholesale paper is a special coated paper, its appearance and ordinary white paper similar. Thermal paper surface is smooth, is by the ordinary paper as paper base, top layer coating thermal hair color layer, coated on one side of the surface of ordinary paper, hair color layer is composed of adhesive, chromogenic agent, colorless dye (or leuco dye), not to be separated, microcapsule chemical reactions in a state of "latent". When the thermal sensitive paper meets the hot print head, the colorant and colorless dye in the print head react chemically and change color, forming the picture and text.

Thermal paper were placed above 70 ℃ environment, thermal coating began to change color. The reason why it changes color also depends on its composition.

There are two kinds of thermal sensitive components in POS Printer Brazil paper coating. The other is a colorant. This kind of thermal sensitive paper is also called two-component chemical thermal sensitive recording paper.

POS Printer Russian Commonly used as colorless dyes are: triphenyltoluene alkyl phthalide system of crystalline purple lactone (CVL), fluorane system, colorless benzoyl methylene blue (BLMB) or spiropyran system. Commonly used as colorant: para-hydroxybenzoic acid and its esters (PHBB, PHB), salicylic acid, 2, 4-dihydroxybenzoic acid or aromatic sulfone, etc.

Thermal paper after heated colorless dye color react with chromogenic agent, so the use of thermal paper receives signals on the fax machine to print or direct thermal printer to print, graphic display. Since there are many varieties of colorless dyes used, the colors of the letters displayed are different, such as blue, magenta, black, etc.
