Abstract
Each of M head units of a print head includes a driving signal generator and a plurality of piezoelectric elements. A common control signal is supplied from a control signal supply portion of a control unit to the respective driving signal generators of the M head units. The driving signal generator of each head unit generates a driving signal from the control signal according to characteristics (for example, relationship of a deformation amount with respect to an applied voltage) of each latter stage piezoelectric element and supplies the driving signal to each piezoelectric element.
