Brother's CUPS drivers are next to useless, because they never update them.
Trying creating a profile for it using the CUPS "Generic Postscript Printer" driver 
and see if that works any better (it did for me on a Brother MFC-9130CW).  If I 
recall correctly, you can have multiple CUPS profiles for the same physical printer, 
and they'll be treated as different logical printers.
