There are at least two ways to store your Litecoin wallet on paper.
One way is using jackjack's version of
pywallet with
--otherversion=48 to dump all the private keys in the wallet. Make sure the client is not running when you run the script.
The easiest way, if you use a recent enough client, is to use the RPC calls
getaddressesbyaccount and
dumpprivkey.
