Abstract
An ink jet includes a variable volume chamber with an ink droplet ejecting orifice. The volume of the chamber is varied by a transducer which expands and contracts in a direction having at least a component extending parallel with the axis ink droplet ejection from the orifice. The transducer communicates with a moveable wall of the chamber which has a sufficiently small are a such that the difference in the pressure pulse transit times from each point on the wall to the ink droplet ejection orifice is less than 1 microsecond.
