The differences are that I replaced the store logo with the order number in big bold letters for easy reference. (and I don't use a store logo anyway, got STS running with a different kind of design), and shows the comments for the order with their added date at the bottom. It's aimed to be printed and referred to when processing, packing then filing orders, makes it a lot easier to handle if there is no computer nearby.
