Now that the world has gone digital, you can save documents in a cloud. You can open an account with Google Drive, Dropbox, and Microsoft OneDrive, among others and keep your documents there. You only need to scan the documents and upload them to your account. Anytime you need them, you download and print.
Most importantly, your password to the cloud accounts should be highly secretive and difficult to guess. It means that even when your hardcopies burn or get lost, you can still download the same copies from your cloud account.
