thanks jtm-lis!
note to others: this package should now automatically place the CUPS filter and PPD into their appropriate respective locations at /usr/lib/cups/filter/ and /usr/share/cups/model/ so all you should need to do now is install this package, enable/start cups, add the printer /w the PPD that should show up under Brother, use either lpd://PRINTER_IP/BINARY_P1 or http://PRINTER_IP/POSTSCRIPT_P1, and go!

To print from my system, I had to add the printer in CUPS as a 'LPD/LPR Host or Printer', and my connection is 'lpd://PRINTER_IP/BINARY_P1' substituting my printer's ip address for PRINTER_IP. Hope this helps someone else.
