Abstract: PURPOSE: To avoid simultaneous urging of two printing elements arranged along a printing direction by providing a data allocating means for allocating two print data isolated at an interval corresponding to that of the two elements along the direction to only one element. CONSTITUTION: At the time of printing by using an A printing wire row in which printing wires A on two adjacent liens along a printing direction are deviated by an even dot amount and a B printing wire row in which printing wires B are disposed by dividing into the same integer dots along the wires A of the A printing wire row and the printing direction, valid data array is obtained by alternately distributing two data to the A and B rows to distribute it to the same rows at the same positions of the direction of a plurality of lines L1, L2, L3,... along the direction. Such a data distribution can be realized by providing circuits at the lines L1, L2, L3,... and setting D-FFs 60, 62 to the same initial states.
