摘要： 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.

摘要： In an example of a textile printing method, a thermally curable ink composition is applied on a fabric substrate. The thermally curable ink composition includes from about 1 wt % active to about 6 wt % active of a pigment that absorbs ultraviolet radiation, infrared radiation, or a combination thereof, based on a total weight of the thermally curable ink composition; from about 2 wt % active to about 20 wt % active of a polymeric binder, based on the total weight of the thermally curable ink composition; and an aqueous ink vehicle. In the method, the pigment of the thermally curable ink composition is selectively heated on the fabric substrate by exposing the fabric substrate to an emission wavelength from a narrow wavelength light source for a total exposure time of 3 seconds or less. The selective heating thermally fixes the pigment to the fabric substrate.

摘要： A technique includes rotating a squeegee roller to regulate a film thickness of ink on a developer roller; and using the developer roller to transfer a portion of the ink from the developer roller to a photoconductive member. The technique includes creating, by an electrode, a potential bias with the developer roller to transfer the ink to the developer roller; and inhibiting flow streaks on the developer roller, where inhibiting the flow streaks includes restricting a flow of ink between the squeegee roller and the electrode.
