PROBLEM TO BE SOLVED: To provide an inkjet recorder whereby an accessing frequency to a printing buffer can be reduced to half, bottleneck in memory accessing is solved, and a high speed as the whole system can be attained, by leading accessing of the second time and afterwards from a FIFO memory side at the time when the same ejection data is distributed to a plurality of heads and printed by temporarily storing data for head ejection into the FIFO memory inside an inkjet printer controller. SOLUTION: Head ejection data stored in the printing buffer is temporarily stored in the FIFO memory present in the inkjet printer controller. Thereafter, the FIFO memory is repeatedly read for an amount of a plurality of nozzle arrays in line with respective ejection timings of the nozzle arrays. Data necessary for designated nozzle arrays is selected from the read ejection data and printed. COPYRIGHT: (C)2006,JPO&NCIPI
