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 an example, a method includes, by logic circuitry associated with a replaceable print apparatus component installed in a print apparatus, responding to a sensor data request received from the print apparatus by returning a first response; receiving a calibration parameter from the print apparatus; and returning a second response which is different from the first response.

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: 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.

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.
