ABSTRACT:
Efficient printing of data containing two types of areas (color and monochromatic) in the direction of sub-scanning is present. Routine feeding is performed in 15-dots feed increments while dots are recorded using black nozzle Nos.1to15during routine monochromatic mode printing (step S2). Minor-feeding is then performed in 3-dot feed increments while the same type of main scanning is carried out in the course of lower-edge monochromatic mode printing (step S4). A position adjusting feed may be optionally performed (steps S6,S8). Five nozzles each for cyan, magenta, and yellow are used, and black nozzle Nos.11to15are used during upper-edge color mode printing (step S10). Minor-feeding is performed in single-dot feed increments. Routine feeding is then performed in 5-dot feed increments while the same type of main scanning is carried out in the course of routine color mode printing (step S12).
