ABSTRACT:
An apparatus and method are disclosed for inkjet printing which includes a piezoelectric member which deforms in response to a voltage to discharge an ink drop, as well as a device for generating an electric field for stabilizing the flight of the ink drop. Additional features include switching the electric field in accordance with image data so that printing large ink drops are stabilized and ink drop anomalies are reduced, while printing of small drops is accomplished without an electric field.
