Abstract
A printing control apparatus is configured to control printing using a print head provided with, on different head chips, a plurality of nozzle groups including a first nozzle group and a second nozzle group configured to eject ink of a same color, with at least a portion of a formation range of each of the nozzle groups overlapping each other. The different head chips is disposed in a direction that crosses an alignment direction of nozzles. The printing control apparatus includes a halftone processing unit configured to generate halftone data specifying a presence or absence of dots for each pixel serving as data to drive the nozzle groups based on image data. The halftone processing unit is configured to generate first halftone data to drive the first nozzle group and second halftone data to drive the second nozzle group in an uncorrelated manner.
