Well you if you own a real printer… a canon it will offer you the poster option for printing.
Look under control panel, printing preferences,poster printing, click specify, also click borderless,
click 11x17 paper size and you need to calculate if the option for landscape or portrait to maximize and not waste paper.
the map is 6x3, use landscape.
divided into 16 (which is 4 x 4 11x17 pages tiled together).
click print range all.
If that does not work let me know and if its something different then i need model number of your printer. At worst case you got to a real printer and a self print shop and make your copy. I hate to use the Kinko services but you may have too.
Trust me on this that you will be very happy with the final product.
