Abstract
A microfluidic printing system for delivering ink to a receive including at least one ink reservoir, a structure defining a plurality of chambers arranged so that the chambers from an array with each chamber being arranged to form an ink pixel for delivery to the receiver, and a plurality of microchannels connecting the reservoir to the chambers. The printing system further includes a plurality of microfluidic pumps each being associated with a single microchannel for supplying ink from an ink reservoir through a microchannel for delivery to a particular chamber. The system is responsive to the flow of the ink through the chambers to determine the amount of ink being delivered to a receiver through the chambers, and further controls the microfluidic pumps to prevent the further flow of ink to the receiver.
