Thermal paper for Android thermal printer

Android POS Terminal is a kind of special coating paper, whose appearance is similar to ordinary white paper. The surface of thermosensitive paper is smooth, which is based on ordinary paper. A thermosensitive chromogenic layer is coated on the surface of ordinary paper. The chromogenic layer is composed of adhesive, chromogenic agent, colorless dye (Android Thermal Printer), which is not separated by microcapsules. The chemical reaction is in a "latent" state. When the heat sensitive paper encounters a heated print head, the color developing agent at the printing place of the print head reacts with the colorless dye to change color, forming a picture and text.

When the thermosensitive paper is placed above 70 ℃, the color of the thermosensitive coating begins to change. The reason of its discoloration should be discussed from its composition. There are two kinds of thermosensitive components in thermosensitive paper coating: one is colorless dye or crypto dye; the other is chromogenic agent. This kind of heat sensitive paper is also known as two group differentiation type heat sensitive recording paper.

The main colorless dyes are: Bluetooth Printer Android, fluorane, blmb or spiropyran. They are mainly used as chromogenic agents: p-hydroxybenzoic acid and its esters (phbB, Bluetooth Printer China), salicylic acid, 2,4-dihydroxybenzoic acid or aromatic sulfone, etc.

When the thermal paper is heated, the colorless dye reacts with the chromogenic agent to produce the color, so when the thermal paper is used to receive the signal on the fax machine for printing or directly printed with the thermal printer, the picture and text will be displayed. There are many kinds of colorless dyes, so the color of the handwriting is different, including blue, purplish red, black, etc.

A working description of a thermal printer

Thermal printing technology was first used in fax Handheld Portable Printer. Its basic principle is to convert the data received by the printer into a dot matrix signal to control the heating of thermal sensitive unit, and heat the thermal coating on the thermal paper to develop. Thermal printers have been widely used in Barcode Label Printer systems, banking systems, medical devices and other fields.

Thermosensitive printers can only use special thermosensitive paper. Thermosensitive paper is coated with a coating that will produce chemical reactions and change color when heated, similar to photosensitive film. However, this layer of coating will change color when heated.

Thermal printers work by installing semiconductor heating elements on the print head, heating the print head and touching the thermal paper to print the desired pattern, similar to the principle of a thermal fax machine. The image is created by heating a chemical reaction in the membrane. This Android Thermal Printer chemical reaction takes place at a certain temperature. High temperatures will speed up the chemical reaction. When the temperature is below 60℃, the paper takes quite a long time, even several years to become dark; Android POS Terminal, the reaction takes place in microseconds.

Classification and era of Label Printer

In the earliest Bluetooth Thermal Printer is the keyboard era, now into an era of everything about intelligence, label printer can not be left behind. So smart label printer came into being, let us enter the intelligent era of label printer. Label printer has keyboard type label printer, touch screen type Barcode Label Printer and app operating version of intelligent portable label printer.

Average person is usually a needle know printer, 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, for example, inside can see thickly dotted with barcode Android POS Terminal, 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 printing, 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 Android Thermal Printer.
