Patent

CA 2289828

A printing device including a laser for generating at least one laser beam, a controller, a print head having a plurality of orifices, and an ink supply for supplying ink to the print head. The controller modulates the at least one modulated laser beam according to image data to be printed. The at least one modulated laser beam selectively generates a directional acoustic wave within the print head, thereby inducing an ink droplet to exit a selected one of the orifices onto a printing substrate. A print head including a single buffer chamber, a body, and a single ink chamber. The buffer chamber stores a buffer liquid therein with the body forming one wall of that chamber. The ink chamber shares the body as a wall. The ink chamber stores ink therein and has a plurality of orifices on a wall opposite to the body.
