ABSTRACT:
An ink jet printer is provided which will print in both the left to right and right to left directions of ink jet head travel with respect to the print media. Relative horizontal displacement of ink jet droplets caused by horizontal travel of the ink jet head is compensated for by a deflection plate system which is tilted with respect to the direction of travel to provide an electric field which tilts the pattern of ink jet droplets in an equal and opposite amount from that caused by horizontal movement of the ink jet head. In one direction of travel an ascending pattern of ink jet droplets is provided and in the other direction of travel a descending pattern of ink jet droplets is provided for printing so that the tilted deflection plate system compensates appropriately for the particular direction of travel.
