    Abstract: A printing device has a reservoir of colorant that is fillable from an external colorant supply temporarily connectable to the printing device. A selectable fill mode of the reservoir is enabled from a number of fill modes. The fill modes include a restricted fill mode in which the reservoir is filled from the external colorant supply responsive to determining that the external colorant supply can be emptied into the reservoir. The fill modes include an unrestricted fill mode in which the reservoir is filled from the external supply regardless of whether the external colorant supply can or cannot emptied into the reservoir. The printing device, responsive to temporary connection of the external colorant supply, controls filling of the reservoir from the external colorant supply in accordance with the selected fill mode.

    Abstract: Example color resources are generated. A first luminosity amount of a greyscale color in a greyscale color space is determined. The greyscale color corresponds with a transformation of a source color in a first color space converted to the greyscale color. The source color corresponding with a depletion color in a second color space, and the depletion color has a second luminosity amount. A target color in a color resource is generated via adjusting a black channel amount in the depletion color to match the second luminosity amount with the first luminosity amount. The target color to correspond with the source color in the color resource.

    Abstract: Examples for cost generation for a common print substance supply are described herein. In some examples, signals indicative of an amount of print substance consumed by a plurality of printing devices are received at a computing device. Signals indicative of a cost corresponding to the amount of print substance consumed by each printing device of the plurality of printing devices are generated at a processor of the computing device based on the received signals. The cost is also generated based on a device identifier, a customer identifier, a print media identifier, or a combination thereof. The signals indicative of the cost for each printing device are transmitted.
