The extrusion module includes a plurality of discrete ink channels each for conveying ink; and a pattern of holes defined in a surface of the extrusion module via which ink from each of said discrete ink channels is fed from the extrusion module to a printhead module. The pattern of holes is repeated longitudinally along the extrusion module. one repetition of the pattern corresponds to one printhead module.
