摘要： A user device transmits to a computing device an authentication code for a virtual printing device consumable item. The computing device authenticates the virtual printing device consumable item using the authentication code. Upon successful authentication of the virtual printing device consumable item, the virtual printing device consumable item is associated with a printing device to permit the printing device to print in accordance with the virtual printing device consumable item. The printing device subsequently prints as permitted by the virtual printing device consumable item.

摘要： The number of days until a consumable item of a printing device reaches end of life is predicted based on a usage scenario of the printing device. An expected fulfillment time period is subtracted from the predicted number of days to determine a number of days until a fulfillment event occurs. A threshold remaining life of the consumable item is correlated with the number of days until the fulfillment event occurs. That the remaining life of the consumable item has reached the threshold remaining life is detected, and fulfillment of a replacement consumable item to replace the consumable item is responsively initiated.

摘要： An example print apparatus is described as including a fuser roller, a pressure device that generates wear on a section of the fuser roller surface, and a wear detection engine that identifies a degree of wear on the surface of the fuser roller. An example fuser roller may include a tube, a heating element, and a plurality of layers having a detectable pattern. An example print apparatus may include a wear detection engine having an emitter, a detector, and a controller that identifies a wear pattern based on data provided by the detector in response to activation of the emitter and determines a degree of wear based on the identified wear pattern.
