Abstract
A circuit for driving first and second groups of actuating elements for ejection of droplets from a printhead, the circuit comprising: a drive circuit configured to provide a drive waveform to first electrodes of the first and second groups; and a voltage offset circuit configured to provide a voltage offset to the second electrodes of the first or second groups to bias the second electrodes of the first and second groups relative to each other.
