Abstract
A print head for an ink-jet printer has a nozzle member defining a plurality of ink channels arranged side-by-side and each terminating in a nozzle. A plurality of actuators are disposed on one side of the nozzle member and respectively face one of the ink channels for pressurizing the ink liquid therein, in order to expel ink droplets through the nozzles. A support for supporting the actuators on the side opposite to the ink channels is provided and a plurality of connecting portions mechanically connect the support to the nozzle member. At least one of the connecting portions is arranged between the actuators. The connecting portions are spaced apart from one another in a longitudinal direction of the ink channels and are formed, for example, by bars extending transversely to the ink channels.
