ABSTRACT:
If data, which is irrelevant to recording data, is stored in a lower address of head word data of the run length compressed recording data stored in a receiving buffer unit, the irrelevant byte data of the lower address of the word data including the head byte data is nullified by masking to be developed by a decode circuit. Otherwise, in regard to a bitmap area of a local memory which is a DMA transfer destination, transfer addresses are individually set by a development processing controller in a DECU per one word of the developed recording data stored in the line buffer in order that data of one line is arranged and stored in a vertical direction, or data of one line is stored in image1and image2in turn. Otherwise, in regard to the development processing controller, when the recording data developed by the decode circuit is stored in the line buffer, it is stored from a first byte in a state where a 0-th byte of the line buffer is vacant.
