PROBLEM TO BE SOLVED: To provide a jetting device with reduced crosstalk.SOLUTION: A printing device for jetting a liquid includes: a flow path body having a plurality of jetting flow paths; a liquid in the plurality of jetting flow paths, a piezoelectric actuator associated with each jetting flow path; a feed substrate having a plurality of fluid inlets; and a driver configured to apply a voltage pulse to the piezoelectric actuator. The first jetting flow path is adjacent to the second jetting flow path and a fluidic travel distance from the piezoelectric actuator of the first jetting flow path to a nozzle of the second jetting flow path is greater than a speed of sound in the liquid times the break off time of a droplet of the fluid from the nozzle. |
