Examples disclosed herein relate to front-to-back registration of a printed content onto a print medium. In one example, a trigger signal generated by a sensor upon detection of a trigger mark on a first surface of a print medium is received. The trigger mark includes a leading edge and a trailing edge, wherein the leading edge and the trailing edge are non-parallel. Based on the trigger signal, a distance of the trailing edge from a point on the leading edge is determined. Once determined, a measure of lateral wander of the print medium with respect to the print path is obtained. The measure of the lateral wander is determined by comparing the distance between the leading edge and the trailing edge, with a threshold value.

A print driver is provided for use in printing a document from a computing device to an extended printing device are provided, the extended printing device being based upon a base printing device. The print driver typically includes a base module configured to process at least one print operation involving printer-specific attributes of the extended printing device that are shared with the base printing device, and an interface module configured to enable an extended module to be added to the print driver to process at least one print operation involving printer-specific attributes of the extended printing device that are not shared with the base printing device.
