That's kind of cool, but doesn't seem very secure.
It probably was decent for the time as long as you printed over a USB cable and not a WiFi network. But since it was a P2PKH address, it could only be spent from once by sweeping it to another wallet.
Cool. I only had a couple bucks worth of bitcoin on a blockchain-dot-infoinfo wallet back then, so I never set up a paper wallet.
I hope you didn’t get rugged on that.
