I Think that could be good that you add a function to print list of passwords. I Mean:
I Use 1password at work (IT Admin) for admin People's passwords for intranet, mail, entrance, etc. so Someteimes I need to print a list of user-passwords so I can take the printed page and go to each employ desktop or anywhere to configure things withot depend of my computer screen.
I think that could be 2 way to do it, and the 2 ways could work together.
First: Print folder of passwords. I Mean I can "on the fly" add loggins to a folder to print or select the Sales department accounts folder and print it.
Second: Add to each loggin account in 1password interface a little button to select it (just like itunes) and then i could have the option to print the selected passwords.
