ABSTRACT:
An inkjet printhead for a franking machine for printing a postage imprint on an item to be franked, which item is displaced relative to the head in a movement direction, said printhead including: a plurality of nozzles disposed in two rows extending transversely to the direction of movement and mounted in respective modules which are mutually offset transversely and lengthwise relative to the direction of movement and which are spaced apart from each other by a distance D in said direction; a first mechanism for moving one module in a direction transverse to the movement direction; and a second mechanism for moving the other module through an angle relative to the direction transverse to the movement direction, which angle is determined so that during printing one end nozzle of one row coincides with one end nozzle of the other row.
