Abstract
Ink jet printing apparatus is provided for vertically randomizing the flight paths of ink drops ejected from an ink jet printing head to print dots at positions randomly deviated vertically with respect to a line scanned by the printing head. Ejected ink drops are passed through an electric field having a randomly varying intensity and direction to randomly deflect the ink drop flight path with respect to a line scanned by the printing head.
