PROBLEM TO BE SOLVED: To provide an inkjet printing system to control actuators in real time. SOLUTION: The inkjet printing system includes a waveform generator 110 to supply electric power, an actuator 120 to change a pressure in an ink chamber when applying a waveform signal from the waveform generator, a sensing unit 130 to continuously sense and output a voltage value for the voltage outputted by the actuator 120, and a controller 140 to sense an inductive voltage value induced by a deformation of the actuator 120 using the sensed result from the sensing unit 130, and to adjust the waveform produced by the waveform generator 110 according to the sensed inductive voltage value, thereby controlling the actuator 120 to have a uniform displacement.
