Abstract
An inkjet printer that has a printhead for printing onto a media substrate, and a reservoir for containing a quantity of ink, the reservoir having a lower portion for holding ink and an upper portion defining a headspace of air above the ink. A fluid connection extends between the printhead and the reservoir. A pump draws air from the headspace to lower its air pressure and thereby controls the hydrostatic pressure of the ink at the printhead.
