Abstract
An ink jet nozzle having more than one fluid resonance in the frequency range of interest is achieved through multi-chamber construction techniques. If the dual resonances are sufficiently close together in frequency, a robust printing region is obtained relatively immune to variations in temperature, drive voltage and ink composition.
