    Abstract: In one example, a powder supply container includes an interior chamber to contain powder, a first basin in the chamber, an outlet from the chamber in the first basin, a second basin in the chamber, and a stallable lift inside the chamber to lift powder out of the second basin into the first basin. The lift is to stall at a stall threshold in which powder in the container prevents the lift from lifting.

    Abstract: In one example in accordance with the present disclosure, a print fluid delivery system is described. The print fluid delivery system includes a main reservoir to hold a volume of print fluid to be supplied to a printhead and a fluid indicator reservoir fluidly coupled to the main reservoir. The fluid indicator reservoir visually indicates a fluid level through an aperture in a printing system housing. The fluid indicator reservoir and the main reservoir have a same fluid level. The print fluid delivery system also includes a fluid transport system to transport fluid through the print fluid delivery system.

    Abstract: In one example in accordance with the present disclosure, a printing device is described. The printing device includes a single thermal printhead that includes an array of heating elements. The array of heating elements are selectively powered to form content on both sides of thermal media passing thereby. Different sides of the thermal media have thermal dye layers with different activation sensitivities. The printing device also includes a media transport system to move the thermal media by the single thermal printhead. A controller of the printing device generates printed content on both sides of the thermal media in a single pass by powering the single thermal printhead based on both content to be formed on a first side and content to be formed on a second side.

    Abstract: A three-dimensional (3D) printer build material spreader cooling system may include a build volume, a build material spreader, a spreader drive, a spreader cooler and a cooling fluid supply. The build material spreader may have a length and a first fluid conduit extending along the length. The spreader drive is to translate the build material spreader across the build volume. The spreader cooler is in thermal conductive contact with the build material spreader. The spreader cooler has a second fluid conduit extending along the length. The cooling fluid supply directs cooling fluid in a first direction through the first fluid conduit and in a second direction, opposite the first direction, through the second fluid conduit.

    Abstract: An example color resource is generated. A source color from a first color space is converted to a corresponding greyscale color in a greyscale color space. The greyscale color includes a first luminosity amount. A black channel amount is adjusted to a depletion color from a second color space to form a target color in the second color space. The depletion color corresponds with a transformation of the source color into the second color space. The depletion color includes a second luminosity amount, and adjusting the black channel includes matching the second luminosity amount in the target color with the first luminosity amount.

    Abstract: A valve mechanism in a supply station for coupling to a build material container and a method for operating the valve mechanism are provided. The valve mechanism includes a valve body having a top opening, a bottom opening, and a front opening. A diverter valve in the valve body is operated by a valve actuator, wherein the diverter valve directs build material from the top opening to the bottom opening when the valve actuator is in a first position and directs build material from the top opening into a build material container through the front opening when the valve actuator is in a second position.
