Abstract
1401728 Printers INTERNATIONAL BUSINESS MACHINES CORP 12 Sept 1973 [13 Oct 1972 22 Jan 1973] 42855/73 Heading G4H In an ink drop printer, deflection means for the ink drops is controlled so that each succeeding drop used in printing a continuous line is caused to print at a position separated from that of the last preceding drop used for that line. This reduces the effect of one drop on the next and so improves print quality. Prior to passing between fixed-voltage deflection plates, the drops are charged by voltages from a D/A converter fed from a counter driven at low or high speed according to whether the corresponding area of a character matrix is to be inked or not (so that non-inked areas are skipped through quickly), the D/A converter being gated off (to produce zero output) in the case of non-inked areas. The counter provides the feature whereby succeeding drops do not relate to adjacent positions in a continuous printed line. A capacitive staircase generator may replace the counter and D/A converter.
