The ink-jet printer was developed after the stylus printer and used a non strike working mode. The outstanding advantages are small size, simple and convenient operation, low printing noise, and the use of special paper can produce pictures comparable to photos, etc.

The ink-jet printer turns the color liquid ink into fine particles through the nozzle and sprays them onto the printing paper. Some ink-jet printers have three or four print nozzles to print yellow, magenta, cyan and black; Some of them share a common nozzle, which is divided into four colors.
