Patent ID: 8526050

Claim:
A data processing device that processes image data to be supplied to a recording head, the recording head comprising a plurality of discharge groups, with each of the discharge groups including a plurality of discharge nozzles that discharge liquid droplets and are arranged in a predetermined direction, the plurality of the discharge groups being arranged in a direction orthogonal to the predetermined direction such that the discharge groups are offset from each other in the predetermined direction, and the recording head being configured to discharge liquid droplets based on image data using the plurality of discharge groups, the data processing device comprising: a first storage section configured to store image data for at least a single line, wherein for each single line, the image data for the discharge nozzles of each discharge group are discontinuously stored in non-adjacent addresses; and a processor that sequentially reads in order image data corresponding to each of the discharge nozzles of each discharge group from the image data of one said single line of said at least one said single line stored in the first storage section and causes the sequentially read image data for each of the plurality of discharge groups to be stored in a continuous storage region of adjacent addresses of a second storage section corresponding to the print head nozzle grouping for storing the image data to be supplied to the recording head such that the image data corresponding to each of the discharge nozzles in the same discharge group are stored as a single continuous block of data.
