A print device may include a refill interface, a processor, and a computer readable medium. The refill interface may have an electrical interface for transmission and reception of signals between the print device and a refill container. And the computer-readable medium may have instructions stored thereon that when executed by the processor are to cause the processor to fetch signals, via the electrical interface of the refill interface, from the refill container indicative of a licensed print functionality of the print device. The instructions may also be to enable the licensed print functionality on the print device responsive to the fetched signals and to maintain the licensed print functionality enabled subsequent to detachment of the refill container.

Print device functionalities

Examples for determining printing device functionality based on consumption and payment are described herein. In some examples, signals indicative of an amount of utilized print consumable by a printing device and signals indicative of payment for the amount of utilized print consumable are received at a computing device. Signals to cause the printing device to alter a functionality based on the signals indicative of an amount of utilized print consumable and the signals indicative of payment for the amount of utilized print consumable are transmitted by the computing device.

Printing device functionality based on consumption and payment

Target color table generated from source color tables. A first significance factor is assigned to a first node in a first source color table. The first node in the first source color table corresponds with a color input in a first color space and provides a first print substance formulation in a second color space. A second significance factor is assigned to a second node in a second source color table. The second node in the second source color table corresponds with the color input in the first color space and provides a second print substance formulation in the second color space. A third node in target color table is generated from the first and second nodes based on the first and second significance factors. The third node corresponds with the color input in the first color space and provides a third print substance formulation in the second color space.
