Your printer is the weakest link here. Some of them apparently store printed files or can be hacked so you need to make sure that is safe or not connected to the net. This is why I don't trust paper wallets as an ideal cold storage option. Any file that has been created digitally and then also printed is gonna make me paranoid as to whether it is 100% safe.

Why don't you just write them down manually, or if you must print them out don't print the full passwords but clues to them or obfuscate them slightly? Depends how complex they are. Ie if your password for this account was password1989 just write p19 or something. Obviously don't use something as simple as that though. Also remember that if other people find your list they could use them as well.
