Abstract: A method performed using a computer includes receiving a cumulative consumption value for a printing fluid corresponding to a supply from a printer at the computer. The method also includes calculating a plurality of variable values by way of the cumulative consumption value for the printing fluid, a statistically derived depletion quantity for the printing fluid, and an estimated time to ship a supply of replacement printing fluid to the printer to form calculated variable values. The method also includes causing the supply of replacement printing fluid to be shipped to the printer in accordance with the calculating.

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: A printer is operable to implement one of a subscription configuration or trade use configuration. The printer can implement one of the subscription configuration or trade use configuration. When the subscription configuration is implemented, the printer restrictively controls, at least temporarily, use of the printing material resource that is installed on the printer. When the trade use configuration is implemented, the printer provides for less or no control over the use of the printing material resource.

Abstract: A cleansing device can trigger a user action to commit the cleansing device to one of a subscription plan or trade use plan. The cleansing device can consume the cleansing material in in accordance with the subscription plan or the trade use plan based on the user action. The controller can commit the cleansing device to one of the subscription plan or trade use plan by persistently implementing a corresponding configuration for the committed subscription plan or trade use plan respectively. When the configuration is implemented for at least the subscription plan, the controller controls the container dispenser in using the cleansing material to be in accordance with a set of rules of the subscription plan, without an ability of a user to manually bypass or override control of the container dispenser in using the cleansing material.

Abstract: Disclosed herein are a system, non-transitory readable medium, and method to manage license to use agreements. The maximum number of credits a device is allowed to consume is determined. An attacker resistant counter is increased using an atomic write.

Abstract: A system for authenticating a user is disclosed herein. An example includes a printer and a printer states code. The example also includes a processor and a support center. Other features of the system are disclosed herein, as are an example of authentication method and a non-volatile storage medium.

Abstract: Example embodiments relate to providing cloud-based printing fluid subscription messages. in example embodiments, the system may then calculate a fulfillment trigger value based on a printing fluid fill level of a printing fluid storage unit and a printing fluid usage history of a remote printing device, where the fulfillment trigger value describes a printing fluid used level of the printing fluid storage unit that triggers an order request for as replacement supply of printing fluid. Next, system may update a subscription fulfillment status for the remote printing device to an order triggered state and send the subscription fulfillment status to the remote printing device, where the remote printing device determines whether to display a printing fluid subscription message based on the subscription fulfillment status.

Abstract: 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.

Abstract: A first, message is output the resource balance is less than or equal to the low value or the device total is greater than or equal to the very low value. A second message is output if the resource balance is less than or equal to the very low value or the device total is greater than or equal to the very low value. Use of the device or resource is stopped until a user acknowledges the second message.

Abstract: A pin associated with an identification number (ID) of a subscription device and a sequence number of a credit is output to a user. The pin is inputted to the subscription device. The subscription device is to allow the user to use a resource up to an extension value stored in the subscription device, if the entered pin correlates to a stored pin of the subscription device.

Abstract: Example embodiments relate to updating key pairs based on digital signature states. In example embodiments, first credentials that are generated using a first private key may be sent to a user computing device, where the first private key is associated with a first public key. At some stage, second credentials that are generated using the first private key and a second private key are sent to the user computing device, where the second credentials specify that the first private key is deprecated, and where the user computing device authenticates the second credentials using the first public key. In response to receiving confirmation that a firmware upgrade is installed a number of user computing devices such that an upgrade threshold is satisfied, the first private key may be deactivated. The firmware upgrade may be provided in response to receiving a firmware upgrade request from the user computing device.

Abstract: Example implementations relate to tangible resources. For example, a method includes receiving, at a computer, a cumulative consumption value of a tangible resource from a device that consumes the tangible resource. The method also includes calculating a plurality of variable values by way of the cumulative consumption value, a statistically derived depletion quantity of the tangible resource, and an estimated time to ship a supply of replacement tangible resource to the device to form calculated variable values such that the calculating is performed at least in part by the computer. The method further includes causing the supply of replacement tangible resource to be shipped to the device in accordance with the calculating.
