Printing apparatus and printing control method

摘要

A printing apparatus and a print control method for performing H-V conversion and minimum track printing at high speed. When printing is to be performed on a print medium by reciprocally scanning a printhead, image data is externally inputted, vertical and horizontal orientation of the inputted image data is converted with considering the print width of the printhead so that the vertical and horizontal arrays are reversed in a buffer of a DMAC, the outputted result is continuously processed by utilizing a logical circuit, the left and right ends where actual printing operation is performed based on the image data is detected within a scan area of the printhead, and the scan area of the printhead is controlled based on the detection result. <IMAGE>
