PROBLEM TO BE SOLVED: To provide a technique for supplying a driving signal with little distortion to an electro-mechanical transducer element without generating excessive heat in a circuit on a carriage. SOLUTION: A second voltage waveform generating part for generating a second voltage waveform changeable according to a first voltage waveform of a driving signal to be supplied to an electro-mechanical transducer element is provided in a printing device main body, and a driving signal supplying part for generating the driving signal for supplying the same to the electro- mechanical transducer element by using the second voltage waveform as the power source voltage and using the first voltage waveform as the control input, is provided on a carriage. |
