摘要：
A side shooting ink ejection device may comprise a front surface, side shooting nozzles having ejection orifices for ejecting fluid, and piezoelectric actuators for moving the fluid through vibration for ejecting the fluid out of the nozzle. The side shooting nozzles may be arranged to eject fluid in a side direction of the piezoelectric actuator. The front surface may comprise recessed portions. The side shooting nozzles may open into the recessed portions so that the ejection orifices are countersunk with respect to the front surface.
