Unable to print Textbox with Table as Background

[BaronCzerny]

I'm using: Word 2010 Spanish
Platform: Windows XP SP3

I want to format my document with a repeating table (one table per page) that contains fixed data, e.g. document title, no. of pages, as if I were working on a preprinted form.



(Note: The commands below are translated from the Spanish, the actual names may be slightly different in the English version of Word 2010.)

Thus I:
1. Click on the Insert tab
2. Click on Header
3. Click on Edit header
4. Click on Textbox
5. Draw a textbox that is nearly as wide and high as the page
6. Remove the border of the textbox
7. Insert a 3-row table, edit the upper and lower rows with the texts I want
8. Close the header
9. Write the text of the main section of the document, applying a page margin that makes this text appear on the middle row.

On screen it looks neat, but when I want to print out the document the table in the background is empty. None of the texts I typed in the table appear.

What I have done wrong?

Thanks for any assistance.
