PROBLEM TO BE SOLVED: To provide an inkjet type printer which can effectively prevent streaks particularly generated due to the unevenness of nozzles at line heads. SOLUTION: To the inkjet type printer equipped with the line heads which can print an image to the whole paper by scanning one head for one direction of the paper, a head unit 106, a head driver part 104 and a nozzle selection part 105 are set. The head unit 106 includes the line head A with a plurality of the nozzles for ink ejection which are arranged on at least one straight line, and the line head B set in parallel to the line head A and with the nozzles for ink ejection which are arranged in parallel to the nozzles of the line head A. The head driver part 104 integrally moves the line head A and the line head B in a scanning direction orthogonal to an arrangement direction of the nozzles. The nozzle selection part 105 selects from which of the nozzles of the line head A and the nozzles of the line head B ink is to be ejected at the moved position. COPYRIGHT: (C)2006,JPO&NCIPI
