Abstract: In an example, a method comprises, by logic circuitry associated with a replaceable print apparatus component, responding to a first validation request sent via an I2C bus to a first address associated with the logic circuitry with a first validation response; and responding to a second validation request sent via the I2C bus to a second address associated with the logic circuitry with a second validation response.

Abstract: In an example, a logic circuitry package has a first address and comprises a first logic circuit. In some examples, the first address is an I2C address for the first logic circuit, and the package is configured such that, in response to a first command indicative of a task and a first time period sent to the first address, the first logic circuit is to, for a duration of the time period, perform a task, and disregard I2C traffic sent to the first address.

Abstract: In an example, a logic circuitry package is configured to be addressable via a first address and at least one second address and comprises a first logic circuit. The first address may be an address for the first logic circuit, and the package may be configured such that, in response to a first command indicative of a first command time period sent to the first address, the package is accessible via at least one second address for a duration of the first command time period; and in response to a second command indicative of a second command time period sent to the first address, the first logic circuit is to, for a duration of the second command time period, disregard traffic sent to the first address.

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: A print substance cartridge for a printing device includes a supply of print substance for the printing device, a non-volatile memory, and logic. The memory stores authentication values by which the print substance cartridge is authenticated by the printing device, and/or a cryptographic key from which a plurality of authentication values are able to be generated within the print substance cartridge. The memory stores hash values corresponding to the authentication values and by which the authentication values are verifiable by the printing device. The logic is to, in response to a request from the printing device for one of the authentication values and including an identifier, provide the authentication value associated with the identifier to the printing device. The logic is to, in response to a request from the printing device for one or more hash values of the hash values, provide the requested one or more hash values.
