Start up Word so it's on a new blank page.
click on File, and then Page Setup, click Paper Size and tick the Landscape box, press OK.
now click on File, then Page Setup, and click on Margins. adjust the margins to 3mm on all sides - this will fit even the 4-disc dvd covers.
click on Insert (top row of commands), and then Picture - scroll onto and click 'From File' - search for the pic you wish to print (or save in word format). Once you've found it click Insert, wait a few seconds for it to copy itself over and then click on File, and then Save As... or Print Preview or whatever you are gonna do to it.
