The writing head comprises thin film elements including marking elements, high and low voltage bus lines, driver circuitry, and switching elements, integrally fabricated upon a large area substrate. A latching circuit, including at least one of the switching elements is located between the pair of bus lines for connecting the marking elements directly to one of the bus lines, so as to insure that the marking elements are always connected to a source of reference potential.
