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.

Abstract: Methods, apparatus, systems and articles of manufacture to control operation of a printer based on whether a marker is detected in a pigment ink are disclosed. Example apparatus include an optical sensor to detect a marker in a vehicle component of the pigment ink. The vehicle is depleted of a pigment component. The apparatus also includes a controller to control operation of the printer based on whether the marker is detected. The apparatus can also include an authorizer to determine whether the printer in which the pigment ink is installed is authorized to use the pigment ink having the marker. The controller of the apparatus is to control operation of the printer by transmitting a control signal to a print head processor to halt printing operations. The apparatus can additionally include a filter to deplete the vehicle component of the pigment component.

Abstract: A logic circuitry package for a replaceable print apparatus component includes a logic circuit and an interface to communicate with a print apparatus logic circuit. The logic circuit is configured to include a plurality of personalities, each personality of the plurality of personalities including an ID and a cryptographic key. The logic circuit is further configured to start a cryptographic session with the print apparatus logic circuit using a selected personality of the plurality of personalities, and transmit a consumable level value to the print apparatus logic circuit in response to a request from the print apparatus logic circuit independent of which personality of the plurality of personalities is the selected personality.

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.
