摘要： A printer may comprise a printhead comprising a number of nozzles, an immiscible fluid applicator, and a processor to instruct the immiscible fluid applicator to apply immiscible fluid onto the surface of the printhead to cap the number of nozzles. A printer subassembly may comprise an immiscible fluid applicator to wipe a layer of immiscible fluid onto a surface of a printhead. A printer may comprise a page wide array printhead, an immiscible fluid applicator to wipe a layer of immiscible fluid over a printhead to cap nozzles over the width of the printhead, and a controller to instruct the printhead to print after the layer of immiscible fluid has been applied over the printhead so that ink ejects through the immiscible fluid while non-used nozzles remain capped by the immiscible fluid layer.

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.
