The frame synchronization words of the preferred embodiment are especially suitable for frame synchronization confirmation. The drive circuitry is partially on one side of the ink chamber with a remainder of the drive circuitry on an opposite side. A multi-colored cable is obtained by changing the color or number of the strands, or by substituting strands or windings of one color for strands or windings of another color during winding. Such devices could be used in a number of different configurations, including one as a stacked set of micro-channel embedded substrates.
