Claim 13:
14. A method for ejecting discrete volumes of ejectant, the method comprising:
supplying with ejectant one or more nozzles of at least one nozzle defined in a rigid body between opposing first and second surfaces of the rigid body, each of the at least one nozzle defined by a conduit extending through the rigid body to connect a first orifice defined at the first surface of the rigid body and a second orifice defined at the second surface of the rigid body, wherein the ejectant is supplied at a pressure above ambient pressure to each of the one or more nozzles through the second orifice of the nozzle; and
moving a gas supply device and the rigid body relative to each other to expose the one or more first orifices of the one or more nozzles to a gas outlet defined by the supply device for supplying the gas at a pressure above the ambient pressure to the one or more nozzles, wherein for each first orifice exposed to the gas outlet, a pressure difference created thereby between the first orifice and the corresponding second orifice causes ejection of the ejectant from the respective nozzle through the second orifice.
