Abstract: Example implementations relate to augmented reality documents. For example, implementations can include device that includes an augmented reality display, and a computing device, comprising a non-transitory memory resource storing machine-readable instructions stored thereon that, when executed, cause a processor resource to: determine dimensions of a piece of media positioned in view of the augmented reality display, and generate an image of a digital document utilizing the determined dimensions on the augmented reality display such that the image is affixed with the piece of media.

Abstract: Examples described herein relate to a system consistent with the disclosure. For instance, the system may comprise a printing device including hardware to adjust a velocity of a development unit within the printing device, a memory resource, and a controller in communication with the memory resource to determine an average usage condition of the printing device, wherein the average usage condition is based on at least one of a print coverage and a quantity of pages printed by the printing device, and adjust a velocity of the development unit based on the average usage condition.

Abstract: In one example method, a determination is made via a processor that a document is to be printed using a printer including a printhead assembly and a printhead accessory based on a received print job. A determination is made via the processor that a first portion of the document is to be printed by the printhead assembly and a second portion is to be printed by the printhead accessory based on a characteristic of the printhead accessory. The first portion of the document is printed via the printhead assembly and the second portion of the document is printed via the printhead accessory.

Abstract: In an example, a method includes extracting a static value and a dynamic value from a computer readable storage device mounted on a consumable that is locked in a printing device. Based at least in part on a comparison of the static value to the dynamic value, it is determined that that the consumable should be unlocked to facilitate removal of the consumable from the printing device. A signal is then sent to a drive mechanism with which the consumable is engaged. The signal instructs the drive mechanism to take an action that unlocks the consumable.

Abstract: In one example in accordance with the present disclosure, a print device is described. The print device includes multiple consumable components. Each consumable component includes a portion of a hardware-based identifier. At least one sensor of the print device reads multiple portions of the hardware- based identifier. A controller of the print device combines the multiple portions of the hardware-based identifier and verifies the hardware-based identifier to determine an authenticity of the multiple consumable components.

Abstract: In an example, a system includes a controller to monitor a usage state of a consumable installed in the system and a drive mechanism to lock the consumable in the system under an instruction from the controller. The drive mechanism includes a shaft to drive the consumable and a key integrated in the shaft to lock the consumable to the drive mechanism.
