Generating a paper wallet online, would just be a mistake. It will be much better if you download the source code from Github and then just
copy it on a air-gapped computer or a old computer that you will not use on the internet. You have to remember that your computer might be
compromised by Malware that records all your activities. < Even when you offline > and also grabs cached information that were send to your
printers buffer. So this method might look easy, but it is the most insecure way to do it. I create all my paper wallets on a old computer &
printer, that will never be used on the internet again.
These computers can be picked up for next to nothing.
