a inkjet printhead containing two substantially closed ink chambers separated by a wall , each of the chambers having associated therewith an electromechanical converter , where actuation of the converter corresponding to a first chamber of said printhead will lead to a volume change in a second chamber due to cross - talk , whereby the wall is deformable in such a way that it deforms by actuation and as such simultaneously generates a second volume change in the same chamber , either volume change being , in essence , the same size but opposite to the other .
