ABSTRACT:
The technique of the invention sequentially supplies dot data to multiple dot formation elements, which are actuated to create dots simultaneously on multiple pixel arrays arranged at preset intervals,and thereby completes a resulting output image on an output medium. The procedure temporarily stores received dot data in a memory, reads out only dot data of the multiple pixel arrays, on which dots are to be created simultaneously by the multiple dot formation elements, converts the read-out dot data into high-resolution dot data, and supplies the converted high-resolution dot data in an order of actual dot formation to the multiple dot formation elements. Dots are sequentially created according to the supplied high-resolution dot data to give a high-quality image. Only the dot data of the multiple pixel arrays, on which dots are to be created simultaneously by the multiple dot formation elements, are set to the current object of resolution enhancement. The converted high-resolution dot data accordingly do not occupy a large memory space. This arrangement desirably ensures output of a high-resolution image without significantly increasing the required storage capacity.
