Printing arcoss 4 pages?

I have made a image that is roughly about A2 size (large hahaha) but I only have a A4 printer so I am having to cut it up in to 4 sections and print each section on its own. now the cropping part is where I may loose some of the image or get it wrong slightly(human error try not to sometimes it just happens:ne:) so my queastion is…Is there a way that I can tell photoshop to print the image(a2 size remember) but print it over seperate pages?
thanx would really appriciate the advice the method at the moment it killing me it takes so long.
