Abstract
A printing device comprising a polymer element capable of switching from an initial state to a final state when subjected to an event, the initial state and the final state being selected from an hydrophilic state and an hydrophobic state provided that the initial state differs from the second state, wherein said polymer element is impregnated with a print fluid, and a controller adapted to generate the event producing the switch of the polymer element, provided that the event is an optical, a thermal or a chemical event, wherein the controller is adapted to generate the event producing the switch of the polymer element on a localized zone and on a internal zone delimited by the localized zone, in order to form a fluid drop at the surface of the polymer element.
