The service manual for Brother HL-22xx (2240, 2250, 2270, etc.) printers says
there is a €œmaintenance device driver€� (which, from documentation Ive
seen, seems to be an app) for windows.

Ive searched the €˜net but cant find this--or other--service apps for
Brother.

Any pointers to any Brother service apps would be greatly appreciated.

Thanks.
