ABSTRACT:
A data control apparatus is structured to execute complementary recording on one pixel array by dividing the scans of a recording head into four. In a nozzle context memory, the nozzle context data, which can be updated, are stored as control data to determine discharge or non-discharge of ink from discharge ports. In an operational circuit, the nozzle context data and image data are processed operationally, thus outputting drive data for the recording head. The data that indicates ink discharge in one pixel array are sequentially assigned to recording data per scan appropriately by use of the nozzle context data and the operational circuit. With the structure thus arranged, it is possible to implement making the capacity of memory smaller for use of data to control recording or non-recording, and also, to execute an intermittent recording by controlling recording or non-recording as required.
