Very Basic and also...

the buttons are not highlighted, so they are non-functional. The only thing that works is manually changing the addresses and their position. It does print on my HP Envy 5535. Whats up with the buttons on app not working?? Its not my iPad, I have the latest version installed. Also if you click above on the Developers Website tab it will take you there and you will find their email address there if you have questions. Whether they answer or not is another matter :/
