Inkjet printhead has an array of ejection chambers spaced in an array direction, each communicating with an ink orifice; inlet an outlet plenum chambers communicating with the ejection chambers; and inlet and outlet manifolds extending in the array direction and communicating with the plenum chambers through a porous sheet. Whilst there are substantial net ink flows in the array direction in the inlet and the outlet manifolds, there is substantially no net flow in the array direction in the inlet or outlet plenum chamber. Ink pressure is therefore constant over the array of ejection chambers.
