Owning a bitcoin paper wallet means the address that holds the bitcoins has not yet been connected to the live blockchain, and so is not "active." Until the wallet is connected to the blockchain, it is considered to be in cold storage (bitcoin jargon for an account being offline).

You can always check the balance of any bitcoin address by searching the blockchain, but to spend it you would need to associate the bitcoin address of the paper wallet to a wallet that is online.

Paper wallets are classed as the most secure method of holding your bitcoins if you do not intend to spend them initially.

When you send bitcoins to an address, they are stored in the blockchain, but to be able to spend them, you will need the private key. As mentioned, this is a long alphanumeric string of characters, and when linked to a bitcoin wallet, any coins associated will be accessible to spend via that wallet. So, a paper wallet is a very secure way of holding your bitcoins, but as with anything involving banking, you need to ensure you look after your private key.

When you create a paper wallet, make sure you are not connected to the Internet: If you are connected, there's a chance that malware could intercept your data, record your private key, and have access to any coins held in your bitcoin address at a later date.
