I would just have this to keep on my wall :)
It's a beautiful hexmap

pdf2png . com has a lossless conversion to png. And imgonline . Com can split images into equal pieces(select no comptession for full detail). I would do 3 tall and 3 wide for letter page prints. Just don't stretch to fill the page when you print and you should be able to have the full size on several pages. The center being a full sheet and the surrounding pages partial pages. There is probably a one stop app but these two are free.
