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: 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: Hardware circuitry, in response to receiving a request for an authentication value of a plurality of authentication values of a replaceable item from a host device to which the replaceable item has been connected, determines that the authentication value was not previously sent. The circuitry responsively determines that the replaceable item previously sent a maximum number of unique authentication values of the authentication values. The maximum number of unique authentication values is less than a total number of the authentication values. The circuitry responsively sends the authentication value to the host device. The circuitry, once the authentication value has been sent or will have been sent to the host device, determines that the maximum number of unique authentication values has now been sent, and in response prohibits the authentication values that have not been sent from being sent later.

Abstract: Disclosed herein are sensor circuits for a replaceable print material container, the sensor circuit to communicate with a printer logic circuit. An example sensor circuit includes a first sensor to detect at least one of a pneumatic stimulus or a pressurization applied by a printer, a second sensor, and an interface to communicate with at least one of a voltage source or a data source of the printer logic circuit. The example sensor circuit also includes logic circuitry, responsive to a class parameter, to: (a) output a first signal based on at least one of the pneumatic stimulus or the pressurization sensed by the first sensor when the class parameter is a first class parameter; and (b) output a second signal based on at least one of an output of the second sensor, different data, or a different algorithm when the class parameter is a second class parameter.

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: In one example, a flexible circuit for a fluid cartridge includes a single flexible substrate, an integrated circuit connected to the single flexible substrate, and an electrical connector pad array arranged in a constant pattern on the single flexible substrate for connection to a host controller. The electrical connector pad array includes first electrical connector pads connected to the integrated circuit and second electrical connector pads for connection to a fluid dispensing die.

Abstract: A replaceable item for a host device, such as a print substance cartridge for a printing device, stores multiple identities. For each identity, the replaceable item stores multiple authentication values, or passwords. The replaceable item selects an identity, and in response to a request for an authentication value from the host device, sends the requested authentication value for the selected identity.
