Laser jet printers are now one of the most important instruments in the marking industry, and their proportions far exceed the traditional labeling and marking machines. For this reason, some of the drawbacks of the printers are slowly emerging. For example, the body shape is too large, and it is not convenient to move the operation, so a small character inkjet printer, a portable inkjet printer such as a hand-held inkjet printer is derived.

Small character inkjet printer, ie dot matrix laser printer. It is suitable for the industry used, because it adopts the non-contact type of coding method, it can smoothly carry out the coding on the surface of various materials, and it is beautiful and clear, and can also freely set the expression form. The small character inkjet printer produces a small logo, usually between millimeters and centimeters. On a narrow surface, it can also successfully complete the marking printing, especially on small products such as cables and electronic components. Fully automatic operation completes the identification work.

The hand-held inkjet printer is suitable for large items that are difficult to move and products that cannot be fixed to form a production line. The size and weight of the printer are small. The inkjet printer can be printed by hand, which is convenient to carry and suitable for manual operation. However, the requirements for manual operation are very high, otherwise the coding effect is very bad.
