My friends in SE team seem to have some passions with the diagrams. That makes the diagram big and cannot fit on a single A4 paper.
To print one of these diagrams onto multiple sheets of A4 paper, you can simply go to Page Setup. And then under the "Print Zoom" section, adjust the "Fit to x sheet(s) across by y sheet(s) down". After that, you can print the diagram as usual by go to File->Print. You will then need the scissors, glue and some hand works :D
