PROBLEM TO BE SOLVED: To manufacture a printing machine with a nozzle head, which is environmentally friendly, does not take too much space, can draw a quick-drying picture and has stably discharged nozzle head. SOLUTION: By employing, as a nozzle head, a filler type or a bimorph cell type small-sized actuator, the pressure in an ink flow passage is properly controlled and mist is jetted on demand in order to form an image. Even when air bubbles enter the ink flow passage, no discharging is not caused. In addition, quicker drying may be allowed by giving ultraviolet rays or heat rays. COPYRIGHT: (C)2009,JPO&INPIT
