What you can do to make a fairly secure paper wallet on a PC:
1. Go to
bitaddress.org2. Right click and save the web page (as a .htm file).
This lets you generate a wallet offline, the wallet generation is done by your computer, not the website.
3. Save that webpage file to a USB.
4. Get a live boot disk/USB for your favorite flavor of Linux. (I use Linux Mint:
http://www.linuxmint.com/download.php)
5. Shut down computer, unplug ethernet. If a laptop, disable the internet after you reboot.
6. Boot to the live CD/USB. The operating system will be loaded in RAM, and it is effectively a "new" operating system.
7. Open that saved webpage on your USB jump drive.
8. Generate Wallet keys, save to that jump drive. Or physically write them down.
When you turn off the computer again, all the data from the live session will be destroyed leaving only the copy on the USB, or your hand written notes. If you print out the PDF later from a normal computer, you should be fine as long as you own the printer you use. Just don't keep the wallet keys stored on a computer connnected to the internet. A flash drive is secure if you do not keep it attached to the computer for more than a few minutes at a time.
