Abstract: A device is to supply printing material to a printing material container in a printing apparatus. The device includes a first container to contain printing material, a first piston movable in the first container to exert first pressure to discharge the printing material contained in the first container from the first container, a second container having an opening to the first container, and a second piston movable in the second container to exert second pressure higher than the first pressure to form a pressure gradient based on the first pressure and the second pressure through the opening. The pressure gradient is to disperse the printing material in the first container.

Abstract: In some examples, a print material particles container can include a print material reservoir, a structure adapted to decrease a volume of the print material reservoir to provide an output of print material particles, and a pressure manipulation device adapted to be manipulated while the volume adapting structure is moved from a first position to a third position to aerate the print material particles.

Abstract: The location of a printing device is determined. Environmental conditions in which the printing device operated when printing a print job are determined based on the determined location. An environmental adjustment factor for the printing device is determined based on the determined environmental conditions. A predicted print material usage of the printing device in printing the print job is adjusted based on the determined environmental adjustment factor.

Abstract: Upon fulfillment of a replacement cartridge of print material, whether projected usage of a printing device will likely deplete a current cartridge of print material prior to anticipated arrival of the replacement cartridge is determined. Responsive to determination that the projected usage will likely deplete the current cartridge prior to the anticipated arrival of the replacement cartridge, the printing device is to enter a reduced print material usage mode during subsequent actual usage of the printing device.

Abstract: In some examples, a computing device can include a processing resource and a memory resource storing instructions to cause the processing resource to determine, based on a geographic identifier of an imaging device, environmental information for a location associated with the imaging device, determine operational information for the imaging device, and select, based on at least one of the environmental information and the operational information, a print material supply for the imaging device.

Abstract: A device to supply printing material to a printing material container of a printing apparatus includes a container including a plunger and to contain the printing material, a portal couplable to a refill port to the printing material container. The portal includes a discharge port through which the printing material is transferrable from the container, and a connector to receive power to move the plunger, to cause a transfer of the printing material contained in the container to the printing material container through the discharge port.

Abstract: That a remaining life of a consumable item has reached a threshold at which piggyback fulfillment of a replacement consumable item is expected to result in arrival before expected continued usage of the consumable item within a printing device results in exhaustion of the remaining life is identified. In response to identifying that the remaining life has reached the threshold, the piggyback fulfillment of the replacement consumable item as part of an order for a user of the printing device using an alternative provider is initiated, rather than default fulfillment of the replacement consumable item using a primary provider being initiated.

Abstract: An image forming apparatus includes a development cartridge having a developing roller. The developing roller includes a roller body, and a shaft to pass through a central axis of the roller body. A coupling structure is disposed at an end part of the shaft, is movable from a first position to a second position, and includes a first coupling piece and a second coupling piece. Positions of the first coupling piece and the second coupling piece are maintained with respect to one another by a static frictional force between surfaces of the first coupling piece and the second coupling piece to hold the coupling structure in the first position. When a predetermined force overcomes the static frictional force, the first coupling piece and the second coupling piece disengage from one another to allow the coupling structure to move from the first position to the second position.
