<P>PROBLEM TO BE SOLVED: To provide an inkjet printer which shortens the time for print processing. Ž<P>SOLUTION: In step S4, offset line image data of nozzles H1 to H192 of each head which have an equal data length each other is formed by adding zero data for only offset number of pixels Ph1 to Ph6 corresponding to the positions of respective heads in the main scan direction A1 to the head of line image data of nozzles H1 to H192 of each head and by adding zero data of a predetermined number to the tail. In step S5, the offset line image data of corresponding nozzles H1 to H192 of all heads formed is collected, and offset line image data group of 192 sets according to the number of nozzles H1 to H192 of each head is composed, and 192 pack data are formed for each same printing timing by packing image data and zero data corresponding to the same printing timing for each offset line image data of each set.
