Abstract: The effect of air resistance acting on ink drops discharged from nozzles of an ink-jet head is appropriately controlled, for example, by means of a method suitable for a breathable medium, such as a cloth and the like. In this way, for example, high-resolution printing, printing with a great gap distance, and the like is properly implemented.

Abstract: To more appropriately carry out generation of a drive waveform signal used in an actuator drive in an inkjet head. An inkjet printer (10) that carries out printing by ejecting ink droplets includes an inkjet head (18) having plural nozzles and plural actuators provided corresponding one to each nozzle, a head control digital signal output unit (108) that outputs a head control digital signal, a digital amplifier (14) that outputs an amplified control signal, which is a signal wherein the head control digital signal has been amplified, a smoothing filter (16) that has plural capacitors and, by smoothing the amplified control signal using at least one portion of the plural capacitors, generates a drive waveform signal, and a capacity specification signal output unit (106) that outputs a capacity specification signal specifying capacitors to be used in smoothing the amplified control signal.
