File > Options > Display > Printing Options > Check 'Print background colors and images'. However I would suggest you don't do that for two reasons.
- Most printers are unable to print to the edge of the page and so you will get an unprinted border around the edge of the page, the width of which is determined by the printer driver.
- Printing backgrounds is very wasteful of ink/toner. Where possible, print on coloured paper instead.
