A medium map is a print control resource object that contains the print control parameters
for presenting pages on a physical medium and for generating copies of the physical
medium. For example, a medium map specifies medium overlays, finishing, rendering

but you cannot see the changes specified in the medium map, the problem might be the
way the AFP file was created or modified.
