With the development of the global economy, the degree of automation and intelligence in industrial production has continued to increase, which has brought great prospects to inkjet printers for inkjet printers. The development of inkjet printers has also undergone many changes (mainly explaining ink inkjet printers), and it has become a more mature form today. The inkjet printer is controlled by software and performs automatic marking and coding in a non-contact manner, which greatly improves work efficiency. It has great advantages in printing countable numbers, variable barcodes and other variable data, and can have anti-counterfeiting functions. Inkjet printers are mainly concentrated in beverage, food, auto parts, electronic components, beer, mineral water, wire and cable, non-staple food, cigarettes, batteries and other industries. In the development history of inkjet printers, the mechanical control system is the most critical, including logic and motion control systems, and has undergone major changes. The development of inkjet printers has changed from pneumatic, ink, and electric pressure ink systems, from the original air pressure to the current built-in pump control system, and then combined with a remote control inkjet communication system or computer. Air circuit, the first generation inkjet printer---air source inkjet printer, simple structure. The air source inkjet printer is driven by an air pump to drive the inkjet printer to the ink circuit pressure of the inkjet printer. The ink pressure is generated by the air pressure, and ink droplets are ejected through the spray cavity. The built-in pump type inkjet printer system is driven by a gear pump and has a complicated structure. The pressure is controlled by a servo motor, which is programmable and adjustable. The third-generation inkjet printer, with mechanical and electronic integration, IC integrated mode, has a more complex structure, adopts a servo system and simple mechanical devices, uses new technologies, has better performance, and is smaller. The continuous development of inkjet technology has made inkjet equipment more advanced, and the development of inkjet printers will develop in the direction of simpler operation, smaller, faster, and higher precision.
