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.
