Printing a Single Image on Multiple Pages?

I need to print large images (A2 and A3) but only have an A4 printer, does anyone know if you can set it up in Photoshop or Illustator (CS3) to print the images but onto multiple A4 page, which I can then assemble together myself. Any help wuld be great as I need to get my work done as soon as possible.

You're going to have to use illustrator, Photoshop doesn't tile images for print.

In Illustrator do File > Print, then a dialog box should come up and at the top left should be a bunch of different options: General, Setup, Marks and Bleed, etc.

Click Setup and under Tiling select, "Tile Full Pages" you then want to give an overlap amount so when you tile the pages after they are printed, it doesnt crop any of the image off.

I usually like to overlap .75 to 1in, you have to trim the prints a little bit, but you get all of your image.

When you're ready, hit print and wait for your prints.
