Abstract
In an ink jet printing device a vibration damping means is provided in the printing head, which comprises an adjustably positionable rigid contact member that engages the surface of the orifice plate at a position remote from the vibration stimulation means that produces high frequency traveling wave vibration longitudinally in the orifice plate. The rigid contact member is preferably resiliently urged into contact with the surface of the orifice plate and is in point contact therewith at a position equidistant from the side edges of the orifice plate.
