Claim 0:
1. An ink delivery system for a printing system, the ink delivery system comprising:
a pressure sensor that is positioned on an ink delivery conduit upstream of the printhead interconnected between a secondary ink reservoir in which ink is stored and a printhead through which the ink is jettable, the pressure sensor being configured to
measure pressure within the ink delivery conduit when the printing system is printing, and
output a signal corresponding to the measured pressure; and

a valve that is fluidly connected to the secondary ink reservoir;
wherein the secondary ink reservoir is configured to be opened to atmosphere through the valve, based on the output signal of the pressure sensor, to maintain stability as the measured pressure changes when the printing system is printing.
