An inkjet print cartridge includes an ink supply and a substrate having a plurality of individual ink ejection chambers defined by a barrier layer formed on a first surface of the substrate and having an ink ejection element in each of the ink ejection chambers to eject ink drops. A nozzle having a plurality of ink orifices formed therein overlies the barrier layer with the orifices aligned and associated with the ink ejection chambers. An ink channel connects an ink supply. A group of the ink ejection chambers in adjacent relationship forms a primitive in which a maximum of only one ejection chamber in the primitive is energized at a time and the primitive is one of a plurality of primitives on the substrate. A first circuit on the substrate is connected to the ink ejection elements and a second circuit on the print cartridge is connected to the first circuit to transmit ejection signals to the ink ejection elements at high frequency. The first circuit applies primitive select signals to select one or more of the primitives and applies address line select signals to enable devices associated with the ink ejection elements in one or more of the selected primitives such that a maximum of one ink ejection chamber in a selected primitive is activated at a time.
