Abstract
The present invention relates to a method of addressing the nozzles of a printhead; a group of nozzles of a print column of the printhead are staggered and are arranged according to a spatial order, e.g. NNNNNNNNNNNN, with respect to the transversal translation direction of the printhead; the nozzle of the group are divided in a number, e.g. 2 or 3 or 4 or 5, of sequential subgroups corresponding to different addressing spaces; an addressing scheme is obtained by cyclically and progressively selecting addresses from these addressing spaces; in this way, it is possible to print with a single pass at different resolutions, higher than the standard resolution of the printhead, by reducing the transversal translation speed of the printhead but maintaining the same addressing timing; the method according to the present invention leaves the possibility of printing at standard resolution and at lower resolutions.
