Advantages and disadvantages of thermal printers

Thermal Printer Supplies technology is the key element, thermal printing machine on a row of tiny semiconductor components, these components close together, ranging from 200 dpi to 600 dpi, these components must be in current through is quickly produce high temperature, when the thermal paper coating meet these components, temperature within a very short time increases, the thermal paper coating chemical reaction occurs, color(80mm Thermal Printer).

After receiving the printed data, the thermal printer converts the Bluetooth Printer Manufacturer printed data into bitmap data, and then controls the heating element on the printing movement through the current according to the point of the bitmap data, thus turning the printed data into the printed content on the printing paper.

Compared with the needle printer, Android Thermal Printer printing speed, low noise, printing clear, easy to use advantages. But thermal printer can not directly print double, printed documents can not be permanently preserved, if using the best thermal paper, avoid light and good state, can be stored for ten years. While needle printing can print double copies, and if a good ribbon is used, the document can be kept for a long time, but the needle printer printing speed is slow, the noise is high, the print writing is rough, and the ribbon needs to be changed frequently. If the user needs to print the invoice, it is recommended to use needle printing, and for other printing of other documents, it is recommended to use thermal printing.

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.

How do I pick out Label printers(2)

Tag content

If you only need to print barcode and text, the general bar code label printer can do. But if you want to print a different bar code (such as POS Printer) or text (such as a shipping label) for each label, and you don't want to stop halfway through the process, you'll need a printer with a 32-bit processor.

Label quality

The printing resolution of tag printer is generally divided into 203dpi, 300dpi and 600dpi. The higher the value of dpi, the better it will print. If you want to print high quality images on labels, consider using a 300dpi WIFI POS Printer head.

Print speed

Different types of printers have different printing speeds, depending on the user's speed requirements. Generally, the printing speed of bar code label printer (Small Portable Receipt Printer) is 2 "-6"/SEC per second, while the printing speed of high bar code label printer (such as M8400RVe) can reach 10 "/ SEC, if a large number of labels need to be printed in a short time, the high-speed bar code label printer should be used

Different industry applications

Bar code printers used in the production line or in the warehouse should be selected with a metal shell model is relatively strong, such as SATO408e/412e; At the point of sale or in the office, you can choose desktop personal printer series, such as ct-400/410, because it requires less space and is easy to move; If the clothing processing enterprises, it is best to choose XL400E/410E this type of code printer is designed for Small Portable Printer manufacturers.
