I think a simple printer is a good investment nowadays (not just for papercraft; me personally, I really enjoy being able to print most of the stuff I want whenever I want at home) but a lot of people also seem to print their papercraft templates at school, or at work, or they ask a friend to do it for them.
I hope you'll be able to print the parts you want one way or another! ;o)
Yea, u can´t, but I found a way to copy the papercraft on paper, even though it will become black and white. I just put an empty paper on the screen, take a pencil and draw it^^ Sometimes it will take veeeeeeeeeeeery long because some crafts are very complicated
Papercraft in general is just cutting out and glueing together pieces of paper, so that's not really hard, no. ;o)
This one has some very small piece (*cough* teeth *cough*) and some other parts that you really need to take your time to figure out how they go together, that make this one a bit more difficult than your average paper model.
