The system comprises, e.g.: (i) an ink supply module including pump, heater and filter that are removable from the printer as a unit; (ii) an ink return module including a pressure transducer, an ink defoaming reservoir and an ink flow-control solenoid that are removable from the printer as a unit; and (iii) a vacuum module including an air pump, an air pressure regulator and an ink collector reservoir that are removable from the printer as a unit.
