ABSTRACT:
A piezo-electric inkjet printing system includes an array of transducers. The array includes at least a first transducer and a second transducer. The first transducer is coupled to a first foot, and elongates in response to a first stimulus, causing ink to eject from a first ink chamber. The second transducer is coupled to a second foot, and elongates in response to a second stimulus, causing ink to eject from a second ink chamber. The first transducer is mechanically isolated from the second transducer.
