If you have Printer in your home, Scan your bitcoin paper wallet as JPG image OR PDF format and save it in a new folder.
Next step is convert this folder as rar OR zip file with password. Then store in your Memmory card, Pendrive, Memmory card, External Hard Disc OR Personal computer. It never become damaged. Hackers never get any informations from a rar OR zip files.
We can extract these files whenever we want. Then we can take prints if needed.
This sounds flawless but I started getting concerned in the latter part of your submission because the memory card can also suffer certain damages so I will rather suggest that you keep the memory card in a safe at the bank or you print out your private keys and have them kept in a bank safe as part of your house and other important documents.
