Abstract: 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.
