This feature allows you to select an image to print an image on the back side of each page. This feature must be used with the following print format parameters:
configured as duplex (vertical or horizontal)
a page layout with one column and one row
no simplex emulation
The backside image is currently applied to both primary and secondary documents if both are configured.
This is a special case feature intended for elimination of pre-printed stock, and not intended for general use with normal rendering processes.
