An object of this invention is to provide a printing apparatus capable of reducing slanting displacement for high-quality image. To achieve this object, slant information of a printing element array (141, 142, 143, 144) in a printhead scanning direction is obtained. Image data used to print by one scanning of the printhead (11) is stored in a printing buffer (204). Image data of three columns used by the printing element array are stored in a transfer buffer (213). Image data of two successive columns out of the image data of three columns are read out from the transfer buffer (213), and image data of a column is selected based on the slant information. Image data of one column is newly read out from the printing buffer (204), and the data area of the transfer buffer corresponding to one column is rewritten. The selected image data is transferred to the printhead (11) for printing. |
