<P>PROBLEM TO BE SOLVED: To enable to judge the need for prior development of a middle code based on an optimal threshold value even if the speed of a printer controller and the speed of a printing engine are reduced. <P>SOLUTION: The controller of an image formation device calculates a loading assessment according to a loading coefficient established corresponding to a middle code about the middle code within a predetermined printing range, memorizes the middle code into a middle code buffer when the loading assessment does not exceed a predetermined threshold value, develops the middle code in advance into the image data and memorizes it into the middle code buffer when exceeding, and further supplies the image data or the image data developed in advance in the middle code buffer into a printing engine while developing the middle code in the middle code buffer into the image data synchronizing with the movement of a printing engine. <P>COPYRIGHT: (C)2008,JPO&INPIT |
