Abstract: In some examples, a container assembly includes a first body to supply a printing composition, the first body comprising a first port, and the container assembly includes a second body to store a reserve printing composition, the second body comprising a second port. An interconnect has a storage position to fluidically isolate the first body from the second body, and a use position to fluidically connect the first body to the second body to allow the reserve printing composition to flow from the second body to the first body to replenish the printing composition in the first body and to allow air in the first body displaced by the reserve printing composition to flow from the first body to the second body. The interconnect in the storage position has a first orientation to fluidically isolate the first port from the second port, and the interconnect in the use position has a second orientation rotated with respect to the first orientation to fluidically connect the first port to the second port.

Abstract: In one example in accordance with the present disclosure a printer cartridge is described. The printer cartridge includes multiple backpressure chambers in fluid communication with a shared free fluid chamber. The backpressure chambers are to supply a fluid to nozzles of a portion of a fluidic ejection assembly and to provide backpressure to the nozzles of the fluidic ejection assembly during deposition of fluid onto a print medium.

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: Examples of a container assembly are disclosed herein. An example of the container assembly includes a first body to supply printing composition and a second body to store reserve printing composition. The example of the container assembly additionally includes an interconnect having a storage position to fluidically isolate the first body from the second body and a use position to fluidically connect the first body to the second body to allow the reserve printing composition to flow from the second body to the first body as needed to replenish the printing composition in the first body and to allow air in the first body displaced by the reserve printing composition to flow from the first body to the second body.
