Abstract: Method of printing fluid on a printable surface of a substrate. A print head ejects fluid in a continuous stream. The print head that includes a micro-structural fluid ejector, which consists of output, elongate input, and tapering portions between the output and the elongate input portions. The output consists of an exit orifice of an inner diameter ranging between 0.1 μm and 5 μm and an end face having a surface roughness of less than 0.1 μm. The print head is positioned above the substrate with the output of the micro-structural fluid ejector pointing downward. During printing, the print head positioning system maintains a vertical distance between the end face and the printable surface of the substrate within a range of 0 μm to 5 μm, and the pneumatic system applies pressure to the fluid in the micro-structural fluid ejector in the range of −50,000 Pa to 1,000,000 Pa.
