ABSTRACT:
The object of the present invention is to provide a printer capable of efficiently processing print data corresponding to a plurality of images in the main scanning direction, as in the case of an index print, with a limited memory capacity, thereby improving the throughput, and an image data processing method for executing the operations of the printer. An image data processing section accesses original image data including partial images of a plurality of images printed through one main scanning, and generates bit image data by executing predetermined image processing. An image data control section temporarily stores the image data in a primary buffer, and when necessary, reads out a part thereof from the primary buffer band by band, copies the read data to a band (secondary) buffer, and sends the data to a print processing section. Therefore, it is no longer necessary to access the original image data to obtain each portion of the partial images and execute predetermined image processing each time when the necessity arises, thereby improving the processing efficiency.
