Abstract
An ink-jet print head (12) for a dot printer, in which the drops of ink are expelled from one or more expulsion chambers (16) through corresponding pluralities of nozzles (30), each plurality communicating with each individual chamber. The nozzles (30) communicating with each chamber may be three to nine in number and are suitably arranged so as to obtain a high print quality in particular for the printing of characters with straight edges free from irregularities.
