An ink containment and delivery system provides high sustained flow rates, allows higher "burst" (short time interval) flow rates, and allows bubble movement through the system conduits to the printhead, all while holding the printhead ink pressure in a range required for optimum printhead operation. The system includes an ink supply with a first, upstream pressure regulator which maintains a negative ink pressure within the ink supply. A second, downstream pressure regulator at the printhead maintains negative pressure in the printhead, and allows some compliance about the set point. The ink containment and delivery system allows drool-free separability of the ink supply and the printhead. |
