setup a new Brother MFC-L2880DWXL for iPad printing ~~~ install two related apps, and do a registration and select the new MFC

I can directly use AirPrint, it works 

or do it the brother way

on the iPad get the Brother iPrint / iScan app

but that is not enough, it ask you the install Brother Mobile connect as well

yeah, better do it, otherwise it won't print!

and when I setup the Mobile connect app, I have to tap registration and select the newly installed MFC,

If I skip this step, it won't print
