The inkjet printer is a device that uses a non-contact method for product identification through software control. According to the font size, it is divided into small character inkjet printers and large character inkjet printers. Small character inkjet printers occupy a dominant position in the inkjet equipment market, but with the continuous development of the inkjet industry, the development environment of small character inkjet printers has various unfavorable factors. After inkjet printers entered the Chinese market, the number of inkjet printer sales companies increased linearly from foreign brands to domestic brands, which led to changes in the market competition pattern, and the threshold for small-character inkjet printers continued to decrease. The profit of small-character inkjet printers is also greatly reduced. The price of consumables for small-character inkjet printers and the unit price of inkjet printers are falling, but the cost of raw materials and labor costs are rising. The era of violent inkjet printers has become a thing of the past. . Third, as domestic inkjet printer companies are springing up in thousands of numbers, many inkjet printer manufacturers continue to fight price wars in order to improve their performance. As a result, the price of inkjet printers is not the lowest but lower. The market environment for small-character inkjet printers is deteriorating and competition is intensifying. In addition, with the coding requirements of many industries, the printing requirements of customers have become more complicated and difficult, and the application range of small-character inkjet printers has gradually failed to meet the needs of the domestic market. In summary, there are more and more obstacles in the development environment of small character inkjet printers. If you want to break through this development bottleneck, rectifying the inkjet printer market and planning it is the first task. The second is to improve the technology of small-character inkjet printers to meet the needs of various inkjet markings.
