摘要： One pixel is sub-divided on the basis of ejection ports. Pixel patterns are provided at respective quantization levels, each of which are defined using dots having different sizes. Image data is processed using a pixel pattern selected according to the type of printing medium and image quality to be achieved, and printing is performed using the image data. Only ejection ports ejecting ink droplets in the same size are driven at the same timing for ejection.

摘要： In a printing apparatus which performs printing by scanning a printhead having printing elements arrayed in a predetermined direction on a printing medium in a direction crossing to the array direction on the basis of information transmitted from a host apparatus, stores print data transmitted from the host apparatus, and has a buffer smaller in capacity than a print data amount printed on the printing medium by one scanning of the printhead, the buffer is divided into a plurality of blocks corresponding to rectangular regions printed by scanning. The use order of the blocks is so managed as to circularly store print data in the blocks along with the progress of printing. When print data representing non-driving of the printing elements successively exist in a predetermined amount, the predetermined amount of print data is represented by specific control data without storing the predetermined amount of print data in the blocks. High-speed, high-quality printing can be achieved with a low-cost arrangement having a memory smaller in capacity than a data amount printed by one main scanning.

摘要： A printing apparatus receives, from a host apparatus, main scanning/printing direction information representing the main scanning/printing direction of a printhead. The printing apparatus stores, in a print buffer, print data corresponding to the printing direction represented by the main scanning/printing direction information generated by the host apparatus. The CPU of the printing apparatus controls printing by the printhead on the basis of the main scanning/printing direction information and the print data stored in the print buffer.

摘要： A recording apparatus is provided with two or more kinds of sub-scanning amounts per main scan, and records a high quality image by reducing the bleeding between colors created characteristically by a multi-pass recording method. The number of times of main scanning to complete an image by a first discharge port array for black ink use and a second discharge port array for color ink use, respectively, are set to be m (m is a positive integer) and n (n is a positive integer) times. With respect to discharge ports to be used for recording in the first and second discharge port arrays, a distance between discharge ports which are positioned at upstream ends of the respective first and second discharge port arrays in the sub-scan direction is made equal to a length of a continuously conveying amount of (m+a) (a is a positive integer) times by combination of the at least two kinds of conveying amounts.
