As others have said, if you sync your OneNote notebook with OneDrive, then you can open it on as many instances of OneNote on as many devices as you want (PC, Mac, Android, whatever).
If you save the notebook as a local file, you can copy and paste or move the notebook.
OneNote 2013 only became free very recently, so that's a new (and cool) thing.
I've taken notes on my SP2 with the stylus in OneNote and had no problem physically printing my notes. I just hit Ctrl + P and I'm done.
