1. to turn off Prices and totals shown on the 'invoice'?
Yes
2. move the position of the customers address?
Yes, but this needs to be done in source code at the moment. However, it a pretty easy adjustment.
Could you please explain how to do this adjustment ? I need to move the delivery address a littlebit more to the right side of my delivery notes. But I'm begginer with PHP so I need your help.
