Just like BottomPrint, except at the top.
If I understand what your saying,you want an upside down print. Its been made if thats what you want.
I think he means in the events where BottomPrint is located, theirs a new event thats called "TopPrint" and the words yuo put in its box appears at the top of the screen.
The problem is that it would require the clients to have the add-on aswell.
