Printing OpenGL Graphics

Hello all!

I have created ( using C, C++ and bash scripts ) an OpenGL program that produces arbitrarily large binary tree structures. I have the ability to zoom and pan but I need to be able to print the ENTIRE tree off on a large plotter and have it legible so I can analyze the nodes. Now, I can zoom out so it will fit on one screen but this becomes illegible when you’re dealing with an exponential number of leaves ( 2^128 for example ). Even though OpenGL clips for you, is there any way I can print the entire tree out with only a portion of it being displayed on my screen?
