PROBLEM TO BE SOLVED: To provide a drive waveform generating device which does not actuate the printing operation of an inkjet printer, even in case an error has occurred in the operation of a waveform selecting means, and a drive waveform generating method. SOLUTION: In the drive waveform generating device, waveform data generated by a waveform data generating means 12, are stored in waveform storage means 14-1 to 14-n, and a waveform data selecting means 16, upon instructions by CPU 10, reads waveform data for generating a desired drive waveform from the waveform storage means 14-1 to 14-n and supplies the waveform data to waveform generating means 18-1 to 18-n and thus the drive waveform is generated. During non-printing, the waveform data selecting means 16 supplies waveform data for anti-ink coagulation waveform to all the waveform generating means 18-1 to 18-n. Therefore, it is possible to prevent a printing operation from being performed with ink jetting from an inkjet head 26 during the non-printing, even in case a waveform selecting means 20 is erroneously actuated.
