How to print an image over several sheets of paper

I want to print a single image that will ultimately be almost 2 metres high, and it's perfectly all right for me to do so by printing several A3 sheets of paper and gluing them onto a big piece of cardboard. How should I go about this? (I'm on Windows XP.)

Poster Printer works with your existing printer to allow you to print documents at a much larger size than would fit on a single printed page

(open source, Windows)

PosteRazor cuts a raster image into pieces which can afterwards be printed out and assembled to a poster. PosteRazor is open source and is available for Windows, Mac OS X, and Linux.
