A printhead assembly including one or more nozzles is described that can include a droplet ejection module. In one embodiment, the droplet ejection module includes a liquid supply assembly, a housing and a droplet ejection body. The liquid supply assembly includes a self-contained liquid reservoir and a liquid outlet. The housing is configured to permanently connect to the liquid supply assembly and includes a liquid channel configured to receive a liquid from the liquid outlet of the liquid supply assembly and to deliver the liquid to a droplet ejection body. The droplet ejection body is permanently connected to the housing and includes one or more liquid inlets configured to receive liquid from the housing and one or more nozzles configured to selectively eject droplets.
