Abstract: A method at a print device may include receiving, from a supply, signals indicative of a print functionality from a set of authorizable functionalities for the print device. The set of authorizable functionalities may comprise: (1) a color depletion print mode, (2) an increased resolution print mode, (3) a refill pump increased speed mode, or a combination thereof. The method may also include enabling the print functionality on the print device based on the received signals.

Abstract: 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.

Abstract: An example print supply includes a non-transitory computer-readable medium. The non-transitory computer-readable medium includes data. The data includes an indication of a schema for the data. The data also includes an indication of an identifier. The data includes an indication of a digital signature. The digital signature is usable to authenticate a type of the data, the schema, and the identifier. The print supply also includes a communication interface. The communication interface is to output the data from the non-transitory computer-readable medium.

Abstract: A print substance cartridge for a printing device includes a supply of print substance for the printing device, a non-volatile memory, and logic. The memory store authentication values by which the print substance cartridge is authenticated by the printing device, and/or a cryptographic key from which authentication values are able to be generated within the print substance cartridge. The memory stores hash values corresponding to authentication values and by which the authentication values are verified by the printing device. The logic is to, in response to a request from the printing device for an authentication value, provide the requested authentication value to the printing device. The logic is to, in response to a request from the printing device for the hash value corresponding to the authentication value, provide the hash value corresponding to the authentication value to the printing device.

Abstract: In one example in accordance with the present disclosure a printer cartridge and memory device containing a representation of a compressed multi-dimensional color table is described. The color table includes at least one low dimensional portion of the multi-dimensional color table storing color transformation information at a first resolution and a number of remaining portions of the multi-dimensional color table storing color transformation information at a second resolution. In the color table, the first resolution is greater than the second resolution and the at least one compressed multi-dimensional color table is to generate a high resolution uncompressed multi-dimensional color table the high resolution being at least as great as the first resolution.

Abstract: A transform wrapper is stored on a memory device and the memory device may be included in a printer cartridge. The transform wrapper may dynamically build a transform map for a printer based on metadata stored at the memory device. The metadata may indicate at least one of a type of depositing material, transform map, print media and printer.
