A printing apparatus includes a head having a nozzle through which ink that contains thermoplastic resin particles and whose viscosity at 50° C. is equal to or greater than 2.1 mPa·s is discharged, a pressure chamber, and a driving element; an ink non-absorptive medium; a heating unit; and a control unit that applies driving signals to the driving element. In the printing apparatus, a discharge waveform generated by the driving signal includes a first expansion-element that expands the pressure chamber, a contraction-element that contracts the pressure chamber having been expanded by the first expansion-element, a second expansion-element that expands the pressure chamber having been contracted by the contraction-element, a third expansion-element that further expands the pressure chamber having been expanded by the second-expansion element, and a connection-element that connects an end terminal of the second expansion-element with a start terminal of the third expansion-element at the same potential. |
