ABSTRACT:
An ink jet printer prints dot matrix characters by removing unwanted drops from a sequence of uniformly spaced drops in an ink jet stream and subjecting the remaining print drops to a vertical raster deflection in timed relation with relative horizontal motion of the jet stream and a record medium. Selected print drops are individually deflected fractional amounts in either the horizontal or vertical direction prior to the vertical raster deflection to cause the selected print drops to be deposited at positions intermediate the coordinate intercepts of a rectilinear matrix pattern to cause dot matrix characters to be printed with arcuate line segments and various angles corresponding with conventional character shapes.
