Abstract
An ink jet recording apparatus includes a printhead that ejects black ink drops and colored ink drops through a plurality of corresponding ink nozzles in accordance with print data. The printhead ejects ink drops when the printhead is moved to scan a recording medium in a forward direction and a reverse direction opposite to the forward direction. The forward and reverse directions are perpendicular to a direction in which the recording medium travels. A print data identifier separates the print data for a line into black print data and color print data. A print data selector supplies one of the black print data and color print data to the printhead when the printhead scans the recording medium in the forward direction, and the other of the black print data and color print data to the printhead when the printhead scans the recording medium in the reverse direction.
