Because of the size of Island Map it's been separeted into 4 different pieces when printing.
The pieces are called Island Map Up Left, Island Map Up Right, Island Map Down Left and Island Map Down Right.
If you use the Link above you'll get the first piece in this window, when that's done push Print.
After the first piece is done, press the Link above to get the second part of the Island Map.
Then when all 4 pieces are printed, get a Scissor and Glue to reassemble the 4 pieces.
