A method of printing includes processing a print job stream to identify
one or more images to be printed on a first substrate. The first
substrate has a substrate attribute, such as paper weight or surface
roughness, which is different from that of a second substrate. A marking
engine is selected to print the identified images on the selected first
substrate. An operating parameter of the marking engine is modified from
a set point for the second substrate to a modified set point for the
first substrate, to accommodate the substrate attribute of the selected
first substrate. The identified images are sent to the selected marking
engine to be printed.
