1. An inkjet printing system comprising:
an actuator comprising a landing pad, a set of electrodes for transmitting a voltage waveform to the actuator, and a membrane with a multi-height dimple, wherein the dimple comprises a first section laterally extending on a first region of the membrane and a second section laterally extending on a second region of the membrane, wherein the first section has an associated height greater than an associated height of the second section, the first section is disposed proximal to an ink inlet end of the actuator, and the second section is disposed proximal to a nozzle of the actuator, and wherein the membrane is configured to be electrostatically pulled toward the set of electrodes when the voltage waveform is applied to the actuator.
