Abstract
A method and apparatus for delivering solvent free marking material to a receiver is provided. A printhead includes a discharge device having an inlet and an outlet with a portion of the discharge device defining a delivery path. An actuating mechanism is moveably positioned along the delivery path. A material selection device has an inlet and an outlet with the outlet of the material selection device being connected in fluid communication to the inlet of the discharge device. The inlet of the material selection device is adapted to be connected to a pressurized source of a thermodynamically stable mixture of a fluid and a marking material, wherein the fluid is in a gaseous state at a location beyond the outlet of the discharge device.
