1. The inkjet printer is developed after the stylus printer, which uses the non impact working mode. The outstanding advantages are small size, simple operation, low printing noise, and the use of special paper can produce pictures comparable to photos. After years of tempering, the technology of inkjet printer has made great progress.
2. Ink jet printers can be divided into piezoelectric ink jet technology and thermal ink jet technology according to the working mode of the print head. According to the nature of ink-jet materials, they can be divided into water-based materials, solid ink and liquid ink printers. We will describe them separately below.
3. Piezoelectric ink-jet technology is to place many small piezoelectric ceramics near the nozzle of the ink-jet printer print head, and apply voltage to them in due time by using the principle that they will deform under the action of voltage. The piezoelectric ceramic expands and contracts, so that the ink in the nozzle is ejected, and a pattern is formed on the surface of the output medium.
