A printer device for realizing correct representation of the gradation. After oozing a quantitation medium 45 from a quantitation medium nozzle 53, the printer device causes an emission medium 49 from an emission medium nozzle 54 for mixing with the quantitation medium 45 for emitting the resulting mixed liquid. During the time which elapses since emission of the quantitation medium 45 from the quantitation medium nozzle 53 until reversion of the liquid surface of the quantitation medium 45 to the opening end of the quantitation medium nozzle 53, the quantitation medium 53 is pressurized in a direction of pulling the liquid surface of the quantitation medium 45 into the quantitation medium nozzle 53. Also, during the time which elapses since the emission of the emission medium 49 from the emission medium nozzle 54 until reversion of the liquid surface of the emission medium 49 to the opening end of the emission medium nozzle 54, the emission medium 49 is pressurized in a direction of pulling the liquid surface of the emission medium 49 into the emission medium nozzle 54.
