Top customer service unit was unfortunately a flop .....

The multifunction printer does a very good job and should deserve 5 stars if it were not a problem when setting up the associated APP and the necessary wireless connection have been:
The printer was not detected by the app (which are all supported devices through the app) Compatibility list there was different information. Email requests this at Brother remained without reply and after a few attempts, I could solve the problem even then.

For those who have problems with the AirPrint:
The printer loses from the power saving mode and its IP address so the app can not find the device in the WLAN. If, on the product menu a static IP address it works flawlessly.
