Abstract: Hard imaging methods and devices are described. In at least some examples, a method includes ejecting a plurality of droplets of a liquid marking agent corresponding to the image to be formed, wherein the droplets of the liquid marking agent individually comprise a plurality of ink particles. The droplets are received upon a transfer member, and after the receiving, at least the ink particles are transferred from the transfer member to media to form a hard version of the image using the media.

Abstract: A printing fluid pen includes a plurality of fluid ports, a pressure regulator in fluid communication with a first fluid port, and a valve in fluid communication with a second fluid port. The first fluid port is to deliver printing fluid to a fluid ejection device, and the second fluid port is to direct printing fluid out of the pen. In response to negative pressure, the valve is to open to enable fluids within the pen to exit via the second port.

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: Fluid is continuously recirculated through a thermal fluid-ejection printhead. Prior to firing a thermal resistor of the printhead to thermally eject a drop of the fluid through a nozzle of the printhead, the fluid is recirculated on-demand through a chamber of the printhead between the nozzle and the thermal resistor. The thermal resistor is fired to thermally eject the drop of the fluid through the nozzle. The fluid has a concentration of solids greater than 12% by volume.

Abstract: A method of preparing a printer cartridge for transport may comprise applying a volume of immiscible fluid to a nozzle bore of a printhead. A printer cartridge may comprise a volume of immiscible fluid deposited into a nozzle bore of a nozzle of the printhead and a layer of immiscible fluid applied over the nozzle bore opening. A printhead die may comprise a volume of immiscible fluid deposited into a nozzle bore of the die and a layer of immiscible fluid applied over the nozzle bore opening.
