Abstract
A print head includes a capillary around an axis of symmetry for a liquid to be printed, the capillary adjoining at least one elastic element and having a nozzle opening which opens into a prechamber. The prechamber has an outlet opening aligned with the nozzle opening of the capillary in its axial orientation of the axis of symmetry and at least one inlet opening for a guide gas. The at least one elastic element forms a guide for the capillary in its axial orientation only. A feed for the liquid to be printed is provided in the capillary. A mechanical oscillation system is provided that includes the at least one elastic element and the capillary with the liquid contained therein. An actuator with a mechanical or magnetic force interaction with the oscillation system is further provided.
