If it's a single page, put
	gsave copy grestore
at the top, provided that the program doesn't do things like flood the page
with white or things like that.

if it's multi-page, then you can (probably) get away with putting the above
line at the top, and after the showpage routine.  I.e., a lot of things have

/sp {showpage} def

at which point, you'd probably want to modify it to

/sp {showpage gsave copy grestore} def

hope this helps,
