A printhead assembly includes elongate, printhead integrated circuits having a plurality of micro-electromechanical ink ejection mechanisms configured to eject ink. An ink distribution assembly, to which the, or each, printhead integrated circuit can be mounted, defines a plurality of converging ink passages in fluid communication with respective ink ejection mechanisms. An ink reservoir is mounted to the ink distribution assembly and defines a plurality of parallel ink channels in fluid communication with respective groups of the passages, such that inks can be fed from the channels to respective groups of the ink ejection mechanisms.
