If you are using a 64bit version of Ubuntu 14.04, have you installed the necessary support for 32bit programs? See Pre-required Procedure (5) at

Can you ping the printer by name? i.e. Does 'ping -c2 BRW441CA84A12D1' show the printer responding?
When I run 'lpstat -t', my Brother device is listed as:
Code:
device for MFCJ825DW: lpd://192.168.0.5/binary_p1
I use the actual IP address rather than rely on the resolution of the printer name.
