Use a QR code. They can be read with a webcam.

I mean, the whole private key is so long you know..
if you think that is bad. Just wait until you have to manage hundreds of them. AES encrypted with a huge ass passphrase. You are just getting warmed up kiddo!

Print the text (just for any case) and QR code next to it. It is far easier read QR nowadays than use some specific scanning software.

what i meant was for private keys for gpg for bitcoin-otc or other use
Now you are just talking crazy talk.

Just thought I would make sure you were familiar with a paper wallet. This is much simpler than printing a binary file.
Each private key is 32 hex bytes... that's all you need! A paper wallet generator such as the one at bitaddress.org will print a sheet of paper wallets and include scannable QR codes for convenience. All generating is done in javascript within your browser and the page needs no internet access (can be saved and run offline) so the server never sees your keys.

hi,
I stumbled upon this program which could print a binary file to physical paper
and restore them later buy just scanning. Program also provides good
redundancy in case the material on paper cant be decoded properly.
Program is open source and is available as a binary for windows.
This could be helpful to store raw private keys in a safe.
