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.
