Are "print" links needed on a website?

What do you think, does a website for a general audience need a "print" link or will the users know how to print the page for themselves (using the browser controls)?

Some background:

• It's not a content-heavy website, so printing won't be a primary usecase.
• The design has a quite heavy background that can make people stop and think before printing the page, therefore having the print option may also give the right signal to the customers that the page can be printed properly.
