It is known that driving an array of ink jet streams presents problems, if the width of the array is of sufficient length that it can resonate at a significantly lower frequency than the design operating frequency. If this case occurs, width mode oscillations will occur and will produce unwanted perturbations in the fluid. These problems may be minimized or eliminated by creating a driver consisting of small point sources of energy. Such a driver is created by dicing PZT into a mosaic pattern consisting of cubic volumes with dimensions of significantly less length or width than the wavelength of the operating frequency.
