ABSTRACT:
An ink-jet printer wherein a pair of horizontal deflection electrodes and a pair of vertical deflection electrodes are disposed in the order named in the direction of travel of ink drops so that the charged ink drops may be deflected in the horizontal direction depending upon the charge on the respective ink drops, but the vertical deflection electrodes are so arranged or shaped or applied with such deflection voltage that the charged ink drops may be deflected in the vertical direction by the same amount, regardless of the charge on the respective ink drops, away from the trajectory of the uncharged ink drops, whereby the ink dots may be aligned along a horizontal line.
