I have a background watermark image in my word document, and it covers
the entire page when viewed in the print layout view. However, when I
look at the print preview, it does not cover the entire page and leaves
some margin on all the four sides. Prints out same as in print preview.

I want the background to print just as seen in the print layout view --
covering the entire page.

The scale option in the 'printed watermark' window does not help. It
simply changes the zoom level of the image but does not affect the
margins in the print preview.

It seems that some master template is inserting the margings -- any
suggestions on how to remove them?
I tried changing margins in the page setup window, but that just
affects the text margings and not the background margin.

Any help would be appreciated.
