Abstract: In one example, a liquid dispensing device includes a printhead assembly having a liquid port through which liquid may move between a removable liquid container and the printhead assembly and an air port through which air may flow to and from the container. A pressure source is operatively connected to the air port to pressurize the container to push liquid from the container through the liquid port into the printhead assembly. A vent is operatively connected to the air port to vent the pressurized container to draw froth from the printhead assembly through the liquid port into the container. In another example, a method for priming a printhead assembly includes pushing liquid from a container into the printhead assembly through a liquid port and then pulling froth from the printhead assembly into the container through the liquid port.
