Printer having print data correction circuit.

摘要

A non-impact printer has a print data correction circuit (16 in FIG. 1, 116 in FIG. 12) for providing a print data correction processing for video signals transmitted from a printing control unit (1 in FIG. 1, 101 in FIG. 12) to produce correction output data or pattern for printing on the basic raster line and other correction output data or patterns for printing on the sub-raster lines. Those correction output data or patterns are supplied to the print head in the form of a real printing data signal. <IMAGE>
