An ink supply system for supplying ink to the print head of an ink jet printer includes a pump arrangement having a pump outlet for supplying ink to the print head from a supply tank through a print head supply line. A closed container communicates with the pump outlet and the print head for holding a quantity of ink therein for providing a second flow of ink to the print head at a static pressure that increases linearly with time. A valve controllably actuated by a solenoid selectively directs a portion of the ink from the pump outlet to the closed container, gradually compressing the air therein as the container is filled. Ink is thereby supplied to the print head at a gradually increasing static pressure, facilitating initiation of production of jet drop streams by the print head.
