It does what it says, so no complaints there. My printer can do more things now than it could have earlier, so this review should definitely be taken as a net positive.
The only annoying parts of using the app is that its difficult to access in iOS context menu for documents. Id love to have a "Brother iPrint" button right there, but unfortunately you have to jump through numerous hoops with every document you print. Hopefully polish will bring a streamlined experience here.
