I think there's a training video that comes with Omega version 2.5. Since you don't list Omega as software you use, I assume you are wanting to print from Flexi. I use both applications but found myself going into information overload trying to deal with the many differences in running an Edge from Flexi vs. Omega (where I have almost 9 years of experience). So I can't help you much if you want to drive the Edge from Flexi. Some others might.
That won't specifically address learning the Edge but that's simply an output device.
You might want to check with Mark Rugen at
GiveMeHelp.com. He may have some tutorials on running the Edge from Flexi.
