(54) Ink spraying device and method


(57) The invention provides an ink-jet printing head comprising an ink chamber having an orifice through which ink is ejected and working fluid chamber separated from the ink chamber by a thermally conductive and thermally expansive membrane and having first and second electrodes, electrically isolated from each other and adapted to pass current through a resistor positioned spaced from and opposite the membrane so as to create bubbles in the working fluid thus to deform the member so as to eject ink through the orifice. A method of spraying ink is also provided.
