Sorry, you're right. Here is an example:
---snip---
%%BeginFile: confidential 1.0 0

userdict begin
/CUPS_confidential where
{pop}
{       % first call: do necessary initialisations
         currentglobal true setglobal
         globaldict begin
         /CUPS_confidential true def             % say not yet called
         end
         setglobal

         % Define the BeginPage stuff to render the watermark to appear
         % beneath the contents of every page
         <<
                 /BeginPage
                 {
                         pop
                         gsave
                         /_WM_str (Confidential) def
                         /Courier [30 0 0 40 0 0] selectfont
                         /DeviceRGB setcolorspace
                         0.6 0.8 1 setcolor
                         currentpagedevice/PageSize get aload pop
                         2 div exch 2 div exch translate 45 rotate
                         newpath
                         _WM_str stringwidth pop 2 div neg 0 moveto
                         _WM_str show
                         grestore
                 }bind
         >>setpagedevice

}ifelse


end %userdict

%%EndFile
---snip---

Note that, in case if a background *image*, the complete image data must be set up as, say, an 
array of strings, or, in case you printer(s) speak(s) PostScript level 3, as contents of a
reusable stream.

Feel free to ask if you have any questions.
