In continuous drop-deflected raster ink jet printing, characters are printed on paper by a pressurized stream of ink 10 which emerges from a nozzle 11, the stream breaking up into discrete drops 12 within a charge electrode 13. Deflection electrodes 14 and 15 cause charged drops 12 to be deflected vertically, in the present instance, to scan ink droplets onto a print receiving medium 16 so as to create characters or other desired images 17. While the drops are deflected vertically, the nozzle 11, charge electrode 13 and deflection electrodes 15 are mounted on a carrier or the like 18 which is moved horizontally in a line parallel with the print receiving medium, in the illustrated instance into and out of the page. As a result of the horizontal movement of the carrier, the flight time of the drops must be corrected.
