Microsoft Word 2003 does not print page border

As the title says today I had a problem with Microsoft word. The page border wasn't printed correctly. Here are the steps to correct it(At least worked for me)
Go to:
- File menu
- Page Setup...
- Select the tab Paper
- Down the Paper Size select Custom Size
- and set Width = 21cm and height = 29cm
- Down to Preview select Apply to Whole Document
and click ok

That worked for me, the page border was printed correctly. I hope this work for you too.
