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.

Abstract: Example implementations relate to secure messages for IoT devices. For example, a system for secure messages for IoT devices may include an IoT device coupled to a network including a plurality of web services. The IoT device may store a service certificate for each of the plurality of web services, generate a secure message for a web service among the plurality of web services using the stored service certificate for the web service, and send the secure message to the web service without first establishing a connection between the IoT device and the web service.

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: In an example, a logic circuit comprising a communications interface including a data contact to communicate via a communications bus, an enablement contact, separate from the communication interface, to receive an input to enable the logic circuit, and at least one memory register, comprising at least one reconfigurable address register. The logic circuit may be configured, such that, when enabled, it responds to communications sent via the communication bus which are addressed to the address held in a reconfigurable address register.

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.
