PyGTK is a very powerful GUI-Toolkit. Nearly everything is well documented, except how to print. I messed around for hours just to solve this problem so I decided to share this cool piece of code!

Ok. Now that I have this, how do I install it so I can use Python from the command line? I need specific step by step procedures. I'm just a newphyte with ZERO programming experience.

This is a GTK application which means you have to install pyGTK before it runs. You can start it from the command line like any other python program too. It doesn't have to be installed, because it is just a script (not a printing library).

You can print an Image by using cairo to render it and then print it just like in this example with pangolayout!
