    • A printer for printing a viscous material at predetermined positions forming pattern on substrate comprises: frame; device mounted to frame with perforations arranged to form pattern; support apparatus coupled to the frame which supports substrate in printing position; and material dispenser with cylindrical chamber to contain viscous material to be printed onto substrate. Chamber has opening for dispensing viscous material which is coupled to the frame. The dispenser is constructed and arranged to be moved along a 1st axis across the device, whilst the viscous material is being dispensed from the chamber. It is moveable in vertical direction allowing material dispenser to be lifted off of the device, and where printer comprises wiping squeegee and material gathering head which collects excess viscous material on the device. The chamber has a cylindrical axis extending along a length of the chamber, and where the cylindrical axis is orthogonal to the 1st axis.
