Abstract
A print module includes a printhead die, an input regulator to regulate input fluid pressure to the die, and an output regulator to regulate output fluid pressure from the die. A method includes receiving fluid at an input regulator to a print module, creating a fluid pressure differential within the print module between the input regulator and an output regulator, flowing fluid from the input regulator through a printhead die and to an output regulator using the pressure differential, and drawing fluid from the output regulator.
