Abstract
A inkjet printhead containing two substantially closed ink chambers separated by a wall, each of the chambers having associated therewith an electro-mechanical 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.
