If so, I may able to find the correct address.
As RoxxR has indicated, if you accidentally wrote the address down wrong on the paper, you can probably still figure out the correct address. If you know the exact date that you sent some bitcoins to the wallet, then it will make it faster and easier to find the correct address. IF you don't have that information, you can still run a program to scan all addresses that have unspent outputs and search for addresses that are similar to what you think the correct address is.
Furthermore, the paper wallet should have a private key on it as well. (if you don't have the private key, then you'll NEVER be able to spend the bitcoins)
Don't share that private key with ANYBODY, but you should be able to re-calculate the correct bitcoins address from that private key.
