Printing apparatus, printing method, and program

A printing apparatus comprising:

• a first head which has a plurality of nozzles each arranged in a first nozzle row and a second nozzle row, each nozzle of the second nozzle row being offset with respect to an adjacent nozzle of the first row at a first pitch in a predetermined direction, the first nozzle row having a first phase and the second nozzle row having a second phase, where phase is the alignment of a nozzle row in the predetermined direction;
• a second head which has a plurality of nozzles each arranged with respect to each other at a second pitch larger than the first pitch in the predetermined direction and which said second head is spaced from the first head by a predetermined distance in a direction intersecting the predetermined direction, the nozzles of the second head having a phase equal to one of the first phase and the second phase;
• and
• a controller which controls the first and second heads so that only the first head prints the contour of a character or a line image and at least the second head prints a portion of the character or the line image other than the contour, when a print image is the character or the line image.
