Abstract:
1. A printing apparatus that prints by scanning a print head with regard to a printing medium, said print head having ink of a plurality of colors and said printing apparatus comprising: a print buffer for being divided into a plurality of first regions corresponding with a scan direction of the print head, each first region being divided into a plurality of second regions corresponding with color; a reception unit for sequentially receiving a plurality of block data corresponding to a first region, wherein the block data contains data corresponding to predetermined color and a color change code representing an end of data, and wherein data corresponding to a plurality of colors are included in a predetermined order in a single block data among the plurality of block data; acquisition unit for reading block data from the reception unit and for acquiring data in a block unit from the block data and for acquiring the color change code from the block data, wherein the acquisition unit generates a first signal when the acquisition unit acquires the data in a block unit and generates a second signal when the acquisition unit detects the color change code; a processor for controlling printing operation of the printing apparatus and for controlling said acquisition unit based on the first signal; and a storage control unit for assigning block data to the first regions of the print buffer and for storing the data acquired by the acquisition unit in second regions of the first regions and changing the second regions to storing on a basis of the second signal generated by the acquisition unit.
