A printing device for digital printing on a print medium is comprised of a wheel rotatable by a motor, a liquid dispenser for depositing a quantity of liquid on the wheel along the outer edge, and an air jet positioned adjacent the outer edge for removing the liquid from the outer edge and directing the liquid toward the print medium as the wheel rotates through the air jet. The outer edge includes a plurality of teeth transport the paint from the dispenser to the air jet. An electronically controlled motor is used to selectively rotate the wheel through the air jet thereby removing a desired amount of liquid from the wheel. The liquid is transported by the air jet toward the print medium. By employing a plurality of such printing devices, a full color digital image can be reproduced on any print medium.
