Background colors are intended for Web pages; they do not ordinarily print.
You can force them to print by checking the box for "Print background colors
and images" at Office Button | Word Options | Display, but be aware that you
will probably not be able to print clear to the edge ("full bleed"), as most
printers have an irreducible nonprintable area required for paper handling.
Even printers that can print "borderless" photos may not be able to print
without borders except on certain paper sizes, perhaps with a special paper
carrier, and certainly by selecting a special setting in the printer
Properties.
