@froyok try Lulu.com, it's a service meant for self publishing. However, you can test print any pdf you upload without it checkinf if you have permission to do so. So you can just grab the GPU Pro 4 pdf and make it a private unreleased book on your account, and order a single test print. Their prices are very low. Last christmas I did this with a copy of The Book of Shaders, and my print was only $8.78.
