摘要：
Methods and apparatus control the ejection of fluid from a nozzle by selectively actuating a fluid actuator that displaces and ejects fluid through an ejection orifice of the nozzle. The methods and apparatus at least partially closing the ejection orifice of the nozzle, while the fluid actuator is inactive, to reduce evaporation of the fluid.
