A type of printing method that does not use pressure (printing pressure). Printing is done by ejecting fine ink droplets from a nozzle and striking them on the printing paper to form a dot pattern. The printing position is moved by either moving the print head, which is centered around the nozzle, horizontally, or by fixing the head and wrapping the paper around a drum and rotating it. Depending on the method of controlling the ink droplets, there are charge control methods and on-demand methods. In the former, ink droplets are continuously ejected while being charged in response to a signal pulse, passed between deflection electrodes and struck at a specified position on the paper, and unwanted particles are collected in a collector called a gutter, forming a dot matrix on the paper.

圧力(印刷圧)を加えないで行う印刷方式の一種。インキの微細な粒子をノズルから噴射させ,印刷用紙上に打ちつけてドットパターンを形成することによって印刷を行う。印刷位置の移動は,ノズルを中心に構成された印字ヘッドを水平方向に送行させるか,あるいはヘッドを固定して用紙をドラムに巻きつけ回転させることによって行われる。インキ粒子の制御方法によって,荷電制御方式とオンデマンド方式とがあり,前者ではインキ粒子を連続的に噴射させながら信号パルスに応じて帯電させ,偏向電極の間を通過させて用紙上の所定位置に打ちつけ,不用な粒子はガターと称する回収器のほうへ収容することによりドットマトリックスを用紙上に形成する。
