PROBLEM TO BE SOLVED: To provide a print controller suppressing the occurrence of banding in an image, a line head printer, and a dot size determining method. SOLUTION: In the printer 1, the quantity of ink droplets ejected from each nozzle 2c is adjusted based on a dot size value set determined for each nozzle 2c and on the value of each pixel of image data so that the greater the longitudinal distance of a dot line 40 between a pair of dots ejected from a pair of nozzles 2c adjacent to each other in the X direction of an ink head 2, the greater the size of the dots ejected from the pair of nozzles. As a result, the printer can suppress the generation of a gap between dots forming the dot line, and suppress the occurrence of banding in the image printed by the ink head 2.
