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 method of applying a cap to a printhead may comprise selectively applying an immiscible fluid to a surface of a printhead in which the immiscible fluid caps a number of nozzles on a number of nozzles defined within the printhead. A printhead may comprise a layer of immiscible fluid in which the immiscible fluid is selectively applied to the surface of the printhead and in which the immiscible fluid caps a number of nozzles defined within the printhead. A printer may comprise a printhead comprising a number of nozzles, an immiscible fluid applicator, and a processor to instruction the immiscible fluid applicator to apply a layer of immiscible fluid to the surface of the printhead.

Abstract: A printing system may comprise a page wide array printhead a capping station, and a number of modular caps comprising a housing to cover a nozzle array of a printhead and a cap coupler coupled to the housing to couple the cap to the nozzle array in which the modular caps are adapted to be coupled to and removed from the nozzle array of the printhead and stored in the capping station.

Abstract: Methods and apparatus for developing a color mapping for mapping colors from a source gamut to an output gamut are described. In an example, defects in a printed output image are used to identify a region of an initial output gamut associated with a defect. A modified output gamut may be developed, the modified output gamut excluding the identified region. A color mapping for use in mapping colors from the source gamut to the modified output color gamut for producing an output image may also be developed.

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.
