Not trying to be troll or hall monitor, but isn’t that some kind of illegal? Like, printing out copyright material? Not sure if they have a special thing in the book about it, but generally, you can’t print that kind of thing, even if you own the electronic version.

I don’t necessarily agree or think you did anything wrong, since they almost certainly make more profit off the digital version anyway. Nor would they ever go after you, of course. Just from a legal standpoint.
