A transient control valve 1 for regulating pressure variations inside an ink cavity 2 from which ink under pressure is squirted to generate ink droplets for printing. During droplet generator startup, the ink inside the cavity experiences several pressure oscillations until a steady state pressure is achieved. Air in the fluid system also renders less stable the system startup. The disclosed valve 1 vents air from the cavity as well as controls pressure variations thereby reducing generator performance variations at startup.
