ABSTRACT:
This invention provides a low-cost printing apparatus and print control method capable of high-quality printing even in the use of a data buffer smaller in capacity than print data necessary for printing by one scanning of a printhead. According to this method, in printing using a small-capacity print buffer, print data is read out for each block of the print buffer divided into a plurality of blocks. Printing is done while the printhead is being scanned. As for printing using print data stored in the final block, printing is performed by one scanning of the printhead using print data stored in all blocks except the final block and print data obtained by sampling part of the print data stored in the final block. Further, printing is performed by the next scanning of the printhead using the remaining sampled data and print data newly stored in all the blocks except the final block.
