发明名称 Printing method and apparatus
摘要 In a printing method which can suppress half band irregularity caused by 2-pass printing and implement high-image-quality printing, image data is distributed into two sets of data for front and rear heads, and each distributed data is distributed into two sets of data, i.e., forward print data and backward print data, thereby allowing 4-pass printing. An image on one line in the main scanning direction is formed by a total of four scanning operations, i.e., reciprocal printing by the front head and reciprocal printing by the read printhead.
