We can make paper wallets from our exported private keys. A good way to achieve this can be to have a copy of our wallet.dat and linux wallet binaries on a USB stick, move the wallet.dat to the ~/.raven location and dump our keys from withing the non-networked LiveCD Linux.
Once the paper wallet generator is open copy and paste the private key in, check that it generates the corresponding public key, if not try and copy and paste our public key as well.
On a encrypted wallet we can unlock our wallet with the following command:
walletpassphrase "passphrase" "timeinseconds"
example:
walletpassphrase very6securE+pasSword 300
Once the wallet is unlock we can dump our key, address is our corresponding public key:
dumpprivkey "address"
Example:
dumpprivkey RBjAZ4fgoXfMC1ujzs7XKreMxJAL1r9fhT
