    Abstract: 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.

    Abstract: According to examples, an apparatus may include a processor and a memory on which is stored instructions that may cause the processor to determine that a user is within a predefined time period prior to a printing device item being scheduled for automatic shipment to the user. The processor may also determine whether a notice condition has been triggered, in which the notice condition is based on a geolocation of the user and/or historical travel information of the user with respect to a facility at which the printing device item is available. In addition, based on a determination that the notice condition has been triggered and while the user is within the predefined time period, the processor may output a message to the user that the printing device item is available for the user to obtain from the facility.

    Abstract: A print material refill container includes a housing and a chamber, within the housing, to contain a print material. The print material refill container includes a physical indicator subject to modification based on an engagement of the physical indicator with an engagement member of a printing device when the print material refill container engages the printing device to deliver the print material to a reservoir of the printing device. The physical indicator indicates an unused condition of the print material refill container when the physical indicator has a first state prior to the modification, and the physical indicator indicates a used condition of the print material refill container when the physical indicator has a second state subsequent to the modification.
