PROBLEM TO BE SOLVED: To sufficiently enhance the quality of printing by modifying a drive wave-form to drive an ink chamber corresponding to the degree of interference from surrounding ink chambers to correct the delivery amount of ink. SOLUTION: If printing data for one line are taken in by successively shifting serial printing data of one pixel one bit to shift registers 11 -1k to take in the data, the data of the shift registers are latched in a latch circuit 3. And the data latched in the circuit 3 are inputted in energizing signal selection circuits 41 -4k . At that time, each of the selection circuits receives two bit data, as reference data, to operate an adjacent ink chamber in addition to one bit data to operate a respective ink chamber to select one of energizing signals TP1-TP8 using those three-bit data, supplying the selected energizing signal to respective head driver to generate a drive wave-form to drive the ink chamber. |
