you print it out, then either

1) take an exacto knife and cut out the pattern (only so far that it stays intact) which i recommend, then with a sharpie mark the pattern and place "X's" on the parts you will remove.

or

2) take the print, tape it to the pumpkin or plastic pumpkin found in the craft stores and with a pin or wire brad, poke dots in to use as a template when you carve, you connect the dots! (this gets tricky)
