ABSTRACT:
The printing head (12) comprises an insulating container (14) for conductive ink (16) which is expelled through a fine nozzle (18) when a voltage pulse is applied between an electrode (56, 57, 40) and a counter-electrode (22). Capillary passages (51, 50) lead to the nozzle (18) to allow formation of an ink meniscus (23) right up until exhaustion of the ink. A vent (69) keeps the pressure inside the container constant. The head (12) is snap fitted onto a carriage with a conductive plate abutted by the counter-electrode (20) and a spring contacting the external part (40) of the electrode. This plate and spring are fed by way of conductive elements sliding along conductive carriage guides.
