Look at this:
http://www.gnu.org/copyleft/gpl.html
"1. Source Code.
The “source code” for a work means the preferred form of the work for making
modifications to it. “Object code” means any non-source form of a work."

So, on further thought. Supplying a printed on paper copy of the source would
not count as providing the source as it is not in the preferred form for
making modifications.
"4. Conveying Verbatim Copies.
You may convey verbatim copies of the Program's source code as you receive it,
in any medium..."
Well, maybe you can supply it on paper and have that count as the preferred
form. I find that a bit odd with all the other lengths they go to.

Well, I want collections in by-sa handled differently. See:
http://zotzbro.blogspot.com/2012/01/ontheneedforastrongercopyleftforby-sa4x.html
However, my proposed changes to 4.x would still allow for this to happen with
GPL and other free programs. If we do that in this round. It either works
with the GPL as it stands or the ball is in the FSF's court.
all the best,
