A method includes receiving, via a microphone at a printer, a voice command based on a tag of an indexed document. The method further includes digitizing the voice command. The method further includes retrieving a supplemental document based on the digitized voice command. The method further includes printing the supplemental document at the printer.

Navigation printing with voice tagging

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.

Providing replacement printing fluid to a printer

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.

System and method for managing subscription and trade based printer supplies

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.

Printer configuration for use of printing material

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.

Credits to use a device and attacker resistant counter

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.

Authentication utilizing encoded data

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.

Cloud-based printing fluid subscription messages

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.

Resource authorization quantities

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.

Use of resource up to extension value by subscription device

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.

Key pair updates based on digital signature states

An inkjet printing system includes a platen adapted to support a print media, a printhead adapted to eject ink into a print zone between the printhead and the platen toward the print media and beyond a first edge of the print media to generate waste ink, a first absorber formed in the platen within the print zone such that the first absorber is adapted to extend beyond the first edge of the print media and absorb the waste ink ejected beyond the first edge of the print media, and a second absorber adapted to contact and absorb the waste ink from the first absorber, wherein the first absorber has a first capillary head and the second absorber has a second capillary head greater than the first capillary head.
