Abstract: Disclosed is a process for depositing marking material onto a substrate which comprises (a) providing a propellant to a printhead, said printhead having defined therein at least one channel, each channel having an inner surface and an exit orifice with a width no larger than about 250 microns through which the propellant can flow, said propellant flowing through each channel, thereby forming a propellant stream having kinetic energy, each channel directing the propellant stream toward the substrate, the inner surface of each channel having thereon a conductive polymer coating; and (b) controllably introducing a particulate marking material into the propellant stream in each channel, wherein the kinetic energy of the propellant stream causes the particulate marking material to impact the substrate.
