A printing device is provided to print ink in a large area by separating a diaphragm from an actuator applying energy to the diaphragm and respectively operating the diaphragm and the actuator. A printing device includes a lower head(100) having a barrier(120) with a chamber(150) storing ink in an upper part of a nozzle plate(110) with an orifice(160) for discharging ink, a diaphragm(130) formed in an upper part of the barrier and a coil(140) formed in an upper part of the diaphragm, and an upper head(200) having a coil(210) in a lower part of a support plate(220) spaced from the lower head corresponding to the coil of the lower head. A stage adjusts the position of the lower head and the position of the upper head according to each direction. The coil is manufactured by patterning after continuously depositing in polyimide film or electroplating.
