Abstract
An inkjet printhead has ink channels separated one from the next by channels walls that are displaceable in response to actuating signals. Groups of adjacent channels are supplied by respective manifolds such that a single displaceable wall bounds channels belonging to adjacent channel groups. A simplification of the construction and manufacture of the printhead results.
