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.
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:
In one example of the disclosure, a subscription is received. The subscription is to authorize a computing device to at least one of dispense or consume a subscription quantity of a resource. An authorization quantity of the resource is calculated according to a formula that considers a parameter attributable to the subscription. The authorization quantity is to authorize at least one of a dispensation or consumption of the resource at the device. The authorization quantity is sent to the device.
Abstract:
A replaceable printer component includes a memory device to store a tag encryption mask and data. The data is stored in a plurality of blocks of the memory device wherein each block is defined by a tag. The tag encryption mask indicates an encryption status of each block of the memory device defined by the tag. The replaceable printer component includes a communication link to communicatively link the memory device to a printer controller when the replaceable printer component is installed in a printing system. The tag encryption mask is stored within a header of the memory device. Each tag defines a type and a length of the data stored in the blocks.
Abstract:
A printer cartridge includes a memory device and at least one compressed color table stored on the memory device. A compressed color table includes a losslessly compressed neutral axis, a number of nodes that correspond to seed color table nodes and a number of delta nodes that correspond to a number of delta tables. The number of delta tables indicate differences between interpolated color table nodes and corresponding actual color table nodes.

Abstract:
Techniques pertaining to printing a document are disclosed. A printer may include a replaceable marking supply that is either an unrestricted trade supply or a restricted subscription supply. The printer may accommodate either of the unrestricted trade supply or the restricted subscription supply at any given moment.
Abstract:
Example implementations relate to tangible resources. For example, a method includes receiving, at a computer, a cumulative consumption value of a tangible resource from a device that consumes the tangible resource. The method also includes calculating a plurality of variable values by way of the cumulative consumption value, a statistically derived depletion quantity of the tangible resource, and an estimated time to ship a supply of replacement tangible resource to the device to form calculated variable values such that the calculating is performed at least in part by the computer. The method further includes causing the supply of replacement tangible resource to be shipped to the device in accordance with the calculating.
Abstract:
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.
Abstract:
A logic circuitry package for a replaceable print apparatus component comprises an interface to communicate with a print apparatus logic circuit, and at least one logic circuit. The logic circuit may be configured to identify, from a command stream received from the print apparatus, parameters including a class parameter, and/or identify, from the command stream, a read request, and output, via the interface, a count value in response to a read request, the count value based on identified received parameters.
