1. Download Ubuntu iso, burn it on DVD
2. Download bitaddress.org html with javascript (
https://github.com/pointbiz/bitaddress.org) and burn it on CD
3. Remove Harddisk of laptop
4. Boot from Ubuntu DVD.
5. Load bitaddress.org local html site from CD.
6. plug in printer
7. print wallets
8. unplug everything from power.
EDIT: put just 10 BTC on one wallet address (better 5 BTC or even better 1 BTC) if practicable! to avoid the damage if a possible but very unlikely address collision occur. then rent a bank safe deposit box and you can forget it for 5, 10 or even 20 years.
I've tried loading the bitaddress html with java from the CD, but I could not load from CD in ubuntu live. So I loaded it on a USB stick, should be fine right?
Also, To withdraw from Stamp, just fill in one of the paper wallets adresses and wait, right? Can I pay a fee to speed it up?
