The burning question is 'why'? If you need to print coloured backgrounds the
best answer is to print on coloured paper.
Most printer drivers will not allow you to print to the edge of the paper
(and if they did the consumption of ink would be astronomical) and so you
will get a white edge all the way around the document.
If insist in this folly, then the following macro will do the trick for all
the documents in a folder (provided they are not protected). Change the RGB
colour index RGB(102, 204, 255) for the actual background colour index you
want to use.
