Print head for an on-demand type ink-jet printer
 A print head for an on-demand type ink-jet printer for jetting ink droplets from a nozzle has a plurality of pressure chambers interconnected with a single nozzle via a plurality of rectifying elements. The rectifying elements have a fluid resistance which is dependent on the direction of the fluid flow therethrough so that the pressure chambers can operate independent of one another to jet ink droplets at an increased frequency from the nozzle.
