How about using a paper wallet with an encrypted private key?
Then it wouldn't matter if someone copied your paper wallet. Because you can't spend from it without the additional key.
bittaddress.org can make those.
From According to Do All Printers Have a Hard Drive? site mentioned:
"Security Considerations
When your business decommissions a leased or purchased output device,
its hard drive can form a security risk because of the prospect of sensitive data remaining on disk...."
So we should all worry about this !

Re Tails Live CD...don't see how that can protect one from a printer's hard drive storing what you print....
