An ink jet printing head is described comprising an ink chamber, an inner face of which comprises a first electrode and an orifice through which ink is ejected, and a second electrode, the electrodes being electrically isolated from each other and adapted to pass current through the ink in the ink chamber so as to create bubbles in the ink and thus to eject ink through the orifice. A method for ink spraying is also described. <IMAGE> |
