    Abstract: In one example in accordance with the present disclosure, at least one print liquid supply interconnected is described. Each print liquid supply interconnect includes a housing movable relative to a printer and tethered via a feed hose to the printer. The housing includes at least one needle to be inserted in a print liquid supply to allow print liquid to move between the print liquid supply and an ejection device and two keyed slots disposed on either side of a first needle to gate insertion to a print liquid supply with protrusions that match the two keyed slots. The housing also includes a guide feature adjacent the first needle extending between a first keyed slot and the first needle and an electrical interface to establish a data transmission path between the print liquid supply and the ejection device, the electrical interface disposed between the first needle and a second keyed slot.

    Abstract: Example implementations relate to a water sense chamber. For example, an appliance may include a water sense chamber having a sensor, the water sense chamber to house a standard water sample. The appliance may also include a processor coupled to the water sense chamber, where the processor is to obtain a liquid sample from fluid used in an operation of the appliance, measure a first property of the liquid sample using the sensor, generate a comparison of the first property and a second property of the standard water sample, and perform an action based on the comparison.

    Abstract: Systems and related methods are described for circulating and printing fluid onto a printer media. In one example, a system can include an air isolation chamber to pool printing fluid circulated within the system. The air isolation chamber can be fluidly connected to a printhead assembly to eject a portion of the printing fluid onto the printer media. The system can further include a pump to pump printing fluid from the air isolation chamber to the printhead assembly. The system can further include a pressure control valve along a return line between the air isolation chamber and the printhead assembly to regulate the flow of unejected printing fluid to the air isolation chamber to control printing fluid pressure over the printhead assembly.
