Abstract
A printer for printing a viscous material at predetermined positions forming a pattern on a substrate. The printer includes a frame, a device having a number of perforations arranged to form the pattern, a support apparatus that supports the substrate in a printing position, and a material dispenser having a substantially cylindrical chamber to contain the viscous material. The chamber has an opening through which the material is dispensed. The material dispenser is positioned over the device and constructed and arranged to dispense the viscous material through the perforations in the device onto the substrate. In embodiments of the present invention, the material dispenser is adapted to receive standard cartridges containing the viscous material, and the printer further includes a pressurized air source for forcing the viscous material from the cartridges into the material dispenser and from the material dispenser through the perforations on the device and onto the substrate.
