Zusammenfassung:	A printhead includes a droplet-forming heater operable in a first state to form droplets from a fluid stream having a first volume traveling along a path direction and in a second state to form droplets from the fluid stream having a second volume traveling along the path direction. A droplet deflector system is positioned relative to the droplet-forming heater, which applies a force to the droplets traveling along the path direction, whereby the droplets having the first volume diverge from the path direction by a greater extent than do the droplets having the second volume. A droplet-steering heater is adapted to selectively asymmetrically apply heat to the stream such that the path direction is changed.
