Abstract
A microfluidic printing apparatus for printing ink pixels on a receiver includes at least one ink reservoir and plurality of microchannels each connected to the ink reservoir. The apparatus further includes a plurality of chambers associated with at least one microchannel which includes a resilient material which, in an ink delivery position, permits ink to be delivered from the microchannel to a chamber and in an ink printing position blocks the flow of ink from the microchannel to the chamber and reduces the size of the chamber to expel ink for printing on the receiver.
