Adobe Acrobat will let you print pages as large as 15,000,000 inches by 15,000,000 inches if you can make it work. I have not found out why my Windows 7-64/Acrobat Pro 9(CS5) combination refuses to print larger than 1 x 1,9 meters - at work with Windows XP and the Standard version I have no such problems, but I seem to remember that XP needed a hotfix to enable large print sizes.
