If you mean that the background was inserted by clicking on
Format | Background | Fill Effects | Picture, then the background
will not print in Word 2002 or earlier. In Word 2003, it is
possible to make such a background print by clicking on Tools |
Options | Print | check the "Background colors and images" box |
OK.

It was inserted through "background-Picture". It was inserted on Office
2003, but the computer it is not working on is Office 2000.
