Abstract: Example implementations relate to the automatic ordering of laundry supplies. For example, an appliance may include a fluid detection sensor to detect an amount of laundry supplies present within the appliance, where the fluid detection sensor is to detect a first level of fluid in a first container in the appliance. The appliance may also include a processor coupled to the fluid detection sensor, where the processor is to compare the first level of the fluid to a predetermined threshold level and automatically send a request to order a new container when the first level of the fluid in the first container reaches the predetermined threshold level and where the request is sent over a network.

Abstract: An example device includes a droplet ejector including a nozzle to eject droplets of a fluid and a target medium to receive the droplets of the fluid. The target medium is separated from the droplet ejector by a gap to be traversed by the droplets. The example device further includes a frame affixing the target medium to the droplet ejector. The target medium is immovably held with respect to the droplet ejector.

Abstract: An example device includes a first substrate including a first array of droplet ejectors to eject droplets of a first fluid. The example device further includes a first target medium immovably positioned relative to the first substrate to receive droplets of the first fluid from a first subset of droplet ejectors of the first array of droplet ejectors. A second subset of droplet ejectors of the first array of droplet ejectors is positioned to eject droplets of the first fluid to miss the first target medium.

Abstract: Example implementations relate to a mixing chamber for laundry supplies. For example, an appliance may include a mixing chamber to receive at least one laundry supply and a processor coupled to the mixing chamber. The processor is to identify a user-specified setting associated with a laundry load, determine a characteristic of the laundry load, calculate an amount of the at least one laundry supply to apply to the laundry load based on the user-specified setting and the characteristic, and provide the amount of the at least one laundry supply to the mixing chamber, where the mixing chamber is to mix the amount of the at least one laundry supply.

Abstract: In one example, a fluid flow structure includes a fluid dispensing micro device embedded in a molding having a channel therein through which fluid may flow directly to the device. The device contains multiple fluid ejectors and multiple fluid chambers each near an ejector. Each chamber has an inlet through which fluid from the channel may enter the chamber and an outlet through which fluid may be ejected from the chamber. A perimeter of the channel surrounds the inlets but is otherwise unconstrained in size by the size of the device.

Abstract: 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.
