Background image doesn't get printed out!

If you check this website http://www.hackstavastergard.com/uthyrning.html you will then see that those 3 houres are background images and when I print them, then they aren’t visible on the paper! What’s only visible is the text and images of the food and the person who is sitting and writing its computer.
Any idéa how I can make it visible in print as well?

Background colours and images are usually controlled by the settings in the users browser so you cannot over-ride them nor should you try.

If images are important content then they should be in the html anyway. Images in the background are for decoration only.

There’s not much else you can do.
