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: 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: A controller for a printing device includes print mode controller to determine whether a first or second print mode is to be used for a print job, and temperature controller to control a printhead temperature at least one of prior to and during printing the print job, the temperature controller to activate a printhead heater to cause the printhead temperature to be raised to a first temperature if the print mode controller determines that the first print mode is to be used, and the temperature controller to activate the printhead heater to cause the printhead temperature to be raised to a second temperature if the print mode controller determines that the second print mode is to be used, the second temperature different from the first temperature.
