Have you ever wanted to create a large poster, something bigger than your standard printer can handle? If so, consider using PosteRazor. PosteRazor can help you “chop up” a large poster and print each piece separately. Put the pieces together with some tape or on a poster board, and voila, you have a larger poster!
Disclaimer, I haven’t tried this free, open source software out myself yet, but Mac World and PC World have reviewed it. Compatible with Windows, Macs, and Linux.
