PROBLEM TO BE SOLVED: To print a high-quality image with accurate gradation in a printer which forms one pixel by using a plurality of shots. SOLUTION: This printer comprises: a printing data reception part 5 for receiving printing data; a printing-data analysis part 6 for extracting a shot pattern by analyzing the printing data received by the reception part 5; a printing control part 7 for setting a printing scanning direction, according to a position of a carriage; and a shot-pattern changing part 8 for changing the shot pattern, when the printing scanning direction set by the control part 7 is different from a printing scanning direction suitable for the shot pattern. Thus, the printer forms the shot pattern for ejecting an ink droplet, from the first shot. COPYRIGHT: (C)2005,JPO&NCIPI
