Abstract
A microfluidic printing apparatus responsive to an image file for printing a plurality of pixels on a receiver. The apparatus includes a plurality of colorant delivery chambers which contain colorants having mobile ions; and channels for delivering colorants to each colorant delivery chamber. A structure for colorant delivery is connected to the channels for controlling the amount of colorants delivered to the colorant delivery chambers. Electric drivers associated with the microfluidic pumps and the microvalves and which operate the microvalves and the microfluidic pumps for delivering the colorant to the colorant delivery chambers.
