An ink delivery system for an ink jet printing system having a printhead for ejecting droplets of ink, the printhead receiving ink at a controlled pressure, the controlled pressure having a specified pressure range that assures stable printhead operation which includes a replaceable ink supply removeably mounted in an ink supply station, and a controllable valve. The valve inlet is in fluid communication with the replaceable ink supply.
