It is (was) a paper wallet I generated in bitaddress.org. I generated it online, in my work. The system is protected by firewall and VPN. Then I printed it in the printer connected in the network.
You made a big mistake. Who knows what kind of malware and keyloggers you have, that can't be detected easily.
No matter how ''safu'' you think your computer is, it's still connected to internet and paper wallet should be printed from website that is download and generated offline.
Nobody knows if your office have hidden cameras or other type of surveillance, but paper wallets should never be used like this.
Another thing is your opinion about one method I'm thinking for generate a paper wallet in bitaddress.org. Everybody tells that the bitaddress' website is safe. Is that so?
Why are you using paper wallets in the first place, and why the heck are you doing this on your work place??
