PROBLEM TO BE SOLVED: To ensure printing with high print quality. SOLUTION: In a method for driving the ink jet head of an ink jet printer comprising a driving waveform data memory means 12, a memory area designating means, a memory control means 11, a digital/analog conversion means 13, a power amplifying means 14 and a drive circuit 4 where conduction of a bidirectional analog switch means 16 is controlled depending on the presence of an ink jet instruction to apply a driving voltage signal to a piezoelectric actuator 17 corresponding to a nozzle for jetting ink, the memory area designating means selects a different driving waveform data depending on the type or the characteristics of a head including the type of ink and the memory control means 11 reads out a driving waveform data to generate a driving voltage signal for driving the head. |
