摘要： In one example of the disclosure, a subscription is received. The subscription is to authorize a computing device to at least one of dispense or consume a subscription quantity of a resource. An authorization quantity of the resource is calculated according to a formula that considers a parameter attributable to the subscription. The authorization quantity is to authorize at least one of a dispensation or consumption of the resource at the device. The authorization quantity is sent to the device.

摘要： In an example, processing circuitry for use with a replaceable print apparatus component comprises a memory and first logic circuit to enable a read operation from the memory and perform processing tasks, the first logic circuit comprising a timer. The processing circuitry may be accessible via an I2C bus of a print apparatus in which the replaceable print apparatus component is installed and may be associated with a first address and at least one second address, and the first address is an I2C address for the first logic circuit. In examples, the first logic circuit is to participate in authentication of the replaceable print apparatus component by a print apparatus in which the replaceable print apparatus component is installed. The circuitry may be configured such that, in response to a first command indicative of a first command time period sent to the first address, the processing circuit 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 as measured by the timer, ignore I2C traffic sent to the first address

摘要： In an example, a logic circuitry package is configured to communicate with a print apparatus logic circuit. The logic circuit package may be configured to respond to communications sent to a first address and to at least one second address. The logic circuitry package may comprise a first logic circuit, wherein the first address is an address for the first logic circuit. The package may be configured such that, in response to a first command indicative of a task and a first time period send to the first address, the package is accessible via at least one second address for a duration of the time period.
