I created a paper wallet using bitaddress.org and spent bitcoins into it using the Coinbase mobile (Android App). I then noticed that the paper wallet cut off part of the private key during printing! They don't leave anough room for the entire private key. I need to get those bitcoins back out of that wallet/address using only the QR code. I can't figure out how to use the Coinbase mobile app to do that. It apparently can send to a QR code, but not receive from one.
