摘要： A drive signal includes a first drive signal and a second drive signal. The first drive signal includes a prior pulse section including a first contraction element and a discharging pulse section including a first expansion element pulling in a meniscus and the second contraction element discharging a droplet of liquid from the nozzle orifice. The second drive signal includes the discharging pulse section and a vibration control pulse section including a second expansion element controlling a residual vibration of the meniscus. A piezoelectric element is driven with the first drive signal when viscosity of the liquid is equal to or more than a first set value and is driven with the second drive signal when the viscosity is equal to or less than a second set value.
