A printhead comprises a plurality of nozzle chambers that house an ink ejection actuator for ejecting ink from said nozzle chamber. An ink jet supply unit connects directly to the printhead which includes a storage chamber for holding ink and for communicating ink to the nozzle chambers. The ink supply unit has a series of spaced apart baffles disposed between the storage chamber and the nozzle chambers which is configured to reduce acceleration of the ink within the unit as may be induced by movement of the portable printer, whilst allowing for flows of the ink to the printhead in response to active demand from the printhead.
