In practical applications, portable inkjet printers often encounter users questioning their application fields. In the process of understanding portable inkjet printers, it often appears that some cannot complete the coding task, while some portable inkjet printers can Easy to solve, here, I will share with you the necessary conditions for portable inkjet printers in practical applications and in the heavy industry. We understand that portable inkjet printers are also known as handheld inkjet printers. Its main working method is known for its lightness and simple operation. Its application fields are also mainly concentrated in large-scale equipment, special parts, frequent information changes, and variable marking positions. It is impossible or difficult to achieve large-scale and streamlined working conditions, such as heavy industry enterprises, on-site construction teams, logistics distribution centers and other places. Many people will ask: Since the portable inkjet printer can complete the heavy industry enterprise identification task, why sometimes it still can't be achieved? Here, Oulance needs to emphasize that there is a synchronization wheel on the portable inkjet printer. Only when the synchronization wheel runs on a relatively flat surface, can it issue a coding instruction to the inkjet printer to achieve coding. In some heavy industry industries, the location where coding is required is relatively special, and there are not enough coding conditions for the printer to run, so portable printers cannot be used. In addition, the surface materials of the products in the heavy industry are different, and the corresponding ink types of the inkjet printers are also different. In many cases, the information marked by the portable inkjet printer is difficult to adhere to the product surface for a long time. This is also the reason why the heavy industry enterprises cannot use the portable inkjet printer. One of the reasons for the code machine. In summary, when choosing a portable printer in the heavy industry industry, the working conditions of the printer and ink adhesion must be considered.
