Abstract: Embodiments of the disclosed subject matter provide a system having at least one carrier gas source, at least one heated container that includes organic material, and a jet array print head that includes a plurality of apertures to print lines on a substrate, and that is connected to a vacuum source. The system includes a pair of gas bearing plates, with a top gas bearing plate and a bottom gas bearing plate, each having a plurality of pressure apertures and vacuum apertures. The top gas bearing plate applies a uniform force to a top surface of the substrate, and the bottom gas bearing plate applies a uniform force to a bottom surface of the substrate. The top gas bearing plate includes a slot configured for the print head to fit within. The vacuum apertures are arranged perpendicular to a direction of travel of the substrate.
