This program is untested by me, use at your own risk. I'm not responsible for any loss of Bitcoins caused by this program.
Storage media fail. Whether it's a hard drive, DVD or an USB stick they all sooner or later fail. If all your backup drives containing your encryption key die, you are in trouble. Hopefully, there is paper to the rescue. It won't replace backing up to external storage, but when all else fails, at least you have a chance to avoid losing your Bitcoins.
Here is a link to this program: http://ollydbg.de/Paperbak/
It's open source, so you can port it to Android, iOS, macOS and Linux rather easily.
It also includes encryption, but don't rely on it. Encrypt your wallet in your Bitcoin program and GPG it too, so it ends up triply encrypted
Download many copies of the tool too (including source code) and put it on your cloud and your storage, so even if it disappears from the Internet, you wouldn't end up with the fancy notepad paper.
Make sure that you can restore your backup before you can rely on it.

Can not see the point to have this (and such) program even if it is open source. Why not use the the old-fashioned way to export private keys via dumpprivkey and print ( or even engrave) them on the media of you choice? One can even use SSS to split them in the secret parts and keep those parts separately and far from prying eyes.
