Abstract
An ink jet printing apparatus comprises a print head, a reservoir, and a rigid articulated support assembly connecting the print head to the reservoir. The support assembly affords two degrees of rotational freedom for allowing adjustment of the print head relative to the reservoir, so that printing can be carried out on surfaces lying in various planes or moving in various directions without tilting the reservoir. The support assembly has an internal channel for conducting ink from the reservoir to the print head, and may be made of a thermally conductive material in order to maintain hot melt inks at the proper operating temperature using heat generated by heating elements in the reservoir and print head.
