摘要

PURPOSE:To miniaturize memory capacity by estimating the time necessary for developing the output data corresponding to each part of a plurality of the partial regions constituting one page in each partial unit and judging whether output data is developed and stored on the basis of the estimated time and an actual required time. CONSTITUTION:When the printing data from a host computer is received by a printing data receiving part 101, the printing data of one page is taken out by a dividing means 102 and divided at every segment. Subsequently, the development estimating time at the time of the development of respective divided printing data on a bit map image is calculated by a calculation means 103 and compared with the paper feed time of one segment by a speed comparing means 104. When the development estimating time is larger, the printing data of the segment concerned is developed on and stored in the bit map image by a segment unit developing and memory means 105 and the printing data of each segment unit is developed on the bit map image by a video data developing and transfer means 106 to be transmitted to a printing mechanism part 107.
