Abstract
Drop-on-demand ink jet printer capable of directional control of ink drop ejection and method of assembling the method. The method comprises a print head body having an ink ejection orifice adapted to poise an ink meniscus thereat about a center axis passing through the orifice. A deflector is coupled to the print head body and is adapted to be in communication with the poised meniscus for lowering surface tension of a region of the poised meniscus. The poised meniscus deflects away from the region of lower surface tension and away from the center axis to define a deflected meniscus, whereby an ink drop separated from the deflected meniscus travels at an angle with respect to the center axis, so that the ink drop can strike a receiver at any one of a plurality of predetermined locations on a print line.
