A printing method for use with an inkjet printer containing a substantially closed ink duct including a nozzle, said duct being operationally connected to an electro-mechanical transducer, the presence of an air bubble in the duct is determined and the air bubble is subsequently eliminated, wherein the elimination of the air bubble takes place by actuating the transducer at a frequency which is lower than the frequency that corresponds to the size of the air bubble in equilibrium, and the amplitude is sufficient to arrange for the ink drops to be ejected from the nozzle. The invention also relates to an inkjet printer which has been modified to use the present method.
