摘要： A printhead has a fluid chamber having an orifice, an associated fluid drop forming mechanism, and an associated fluid drop steering device. The fluid drop forming mechanism is operable to apply to fluid present in the fluid chamber energy sufficient to cause a fluid drop to be ejected from the orifice. The fluid drop steering device is operable to optionally apply to fluid present in the fluid chamber energy insufficient to cause drop formation prior to the fluid being ejected from the orifice. The fluid drop steering device is distinct from the fluid drop forming mechanism.
