I am doing a similar thing with a Battlemech I'm "biggifiying" for my son. Going from 28mm to somewhere around 1/6 so he can use it with his Star Wars action figures. Although I went to Kinko's and had it printed in black and white on regular paper since I'm going to add greeblies and repaint it anyway. I've actually become a fan of taking a model to a print shop. If you buy your own cardstock, the cost of getting one printed, even in color, is still around 50 cents a page. And it's better quality than I can get off my printer at home.
