Abstract
When print data is stored as index data, a dedicated FIFO memory is interposed between a data processing circuit before index expansion, and an index expansion circuit, and temporarily stores the index data. The stored index data is read out by specifying a portion required for the process of a printhead, thus improving the memory access efficiency and throughput.
