The thermal label printer is a dedicated printer. The biggest difference between thermal label printers and ordinary printers is that thermal label printing is based on heat and directly uses thermal paper to complete the printing. The biggest advantage of this printing method over ordinary printing methods is that it can be left unattended. In the case of continuous high-speed printing.

The working principle of a thermal printer is that a semiconductor heating element is installed on the print head. After the print head heats and contacts the thermal printing paper, the required pattern can be printed. The principle is similar to that of a thermal fax machine. The image is generated by heating, causing a chemical reaction in the film. This thermal printer chemical reaction is carried out at a certain temperature. High temperature will accelerate this chemical reaction. When the temperature is lower than 60°C, it takes a long time, even several years, for the paper to become dark; and when the temperature is 200°C, this reaction will be completed in a few microseconds.

Thermal label printing products have a wide range of applications, so their customer groups are more complex, which can be subdivided into three types of customers: general, industry and ODM/OEM. For general customers, such as commercial/retail, catering, logistics and other application fields, the seasonal impact is not obvious, but due to the constraints of regional economic development factors, the demand in North China, East China, and South China is large, and the demand in other regions is small; Industry customers, such as post, railway, highway and other fields, are affected by the implementation cycle of industry projects and have seasonal characteristics. Generally, the fourth quarter is the peak of procurement, so the company's operating income in the second half of the year has a higher proportion; for ODM/OEM customers , Mainly system integrators and well-known brand product suppliers, whose product demand has unexpected and uncertain factors. The replacement cycle of thermal label printers is generally 5-6 years. Because the thermal label printer market in North America and Europe has basically matured, about 80% of the annual sales volume is for equipment update needs.

The label printer market in China started in the 1990s. In recent years, with the continuous rapid growth of China’s economy, the "Three Gold Projects" and other electronic information management continue to advance, as well as business/retail, finance, communications, transportation/transportation With the continuous improvement of industry service levels, the demand for label printers is increasing rapidly. At present, the application of thermal label printers in my country has entered a period of rapid popularity, and the market scale continues to grow rapidly. Data show that from 2015 to 2018, the average annual compound growth rate of sales of my country's thermal label printer market reached 10.3%, far higher than the global 4.9%; in 2015, the Chinese market accounted for only 10.8% of the global market. By 2018, its share of the global market has risen to 18.6%.
