Abstract: 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.

Abstract: Methods and apparatus to selectively control ink evaporation in printhead nozzles are disclosed. An example printhead for use with a printer includes a plurality of nozzles (142) and a plurality of valves (144) positioned adjacent respective ones of the nozzles (142) to selectively control fluid flow through the respective nozzle (142).

Abstract: Methods and apparatus to control a heater associated with a printing nozzle are disclosed. A method comprising controlling a heater associated with a printing nozzle to reduce a heat output of the heater based on a determination that the printing nozzle is outside a print area and printing an image on a substrate using other printing nozzles while the heat output of the heater is reduced.

Abstract: A printer is disclosed herein. The printer has a printhead having a plurality of ink nozzles for ejecting ink, a servicing mechanism for capturing the ejected ink from the ink nozzles, to service the printhead, and a control device coupled to the printhead and the servicing mechanism for regulating the servicing. As part of the regulation, the control device continues feeding a substrate towards the printhead during an idle period. The idle period of the printhead can be a duration when printing on the substrate is suspended. Further, the control device regulates ejection of ink from the ink nozzles towards the substrate during the idle period and operates the servicing mechanism during the idle period. In an example, the servicing mechanism captures the ink before the ink reaches the substrate.
