It is not advisable that you use wine to install drivers for any hardware, as they won't be properly integrated into ubuntu.

However here is a step by step guide to get the drivers working (if you're on an 64-bit system):

First unplug your printer.

Open a terminal and copy&paste the following commands

sudo apt-get remove brother-lpr-drivers-laser brother-cups-wrapper-laser

(removes any existing drivers that could cause conflict)

sudo apt-get install --reinstall cups csh lib32stdc++6

(reinstalling dependencies)

sudo mkdir -p /var/spool/lpd/

sudo mkdir -p /usr/share/cups/model/

(make directories for the drivers)

mkdir -p ~/Downloads/brother/

cd ~/Downloads/brother/

(make download location)

wget http://pub.brother.com/pub/com/bsc/linux/dlf/brdcp7030lpr-2.0.2-1.i386.deb

wget http://pub.brother.com/pub/com/bsc/linux/dlf/cupswrapperDCP7030-2.0.2-1.i386.deb

(download drivers)

sudo dpkg -i --force-architecture brdcp7030lpr-2.0.2-1.i386.deb

sudo dpkg -i --force-architecture cupswrapperDCP7030-2.0.2-1.i386.deb

(install and configure driver packages)

sudo ln -s /usr/lib/cups/filter/brlpdwrapper* /usr/lib64/cups/filter/

(link driver files)

plug in your printer now and proceed with the installation process from 'System Settings' -> 'Printers'

To enable scanning:

sudo apt-get install --reinstall sane-utils xsane xsane-common

Download Scanner drivers from brother home page (64-bit):
http://www.brother.com/cgi-bin/agreement/agreement.cgi?dlfile=http://www.brother.com/pub/bsc/linux/dlf/brscan3-0.2.11-4.amd64.deb&lang=English_gpl

(32-bit)
http://www.brother.com/cgi-bin/agreement/agreement.cgi?dlfile=http://www.brother.com/pub/bsc/linux/dlf/brscan3-0.2.11-4.i386.deb&lang=English_gpl

plug in and turn on your scanner
open a terminal and type

sudo dpkg -i --force-all ~/Downloads/brscan3-0.2.11-4.amd64.deb

(for 64-bit)

sudo dpkg -i --force-all ~/Downloads/brscan3-0.2.11-4.i386.deb

(for 32-bit)

check if it installed correctly

dpkg  -l  |  grep  Brother

output should look something like this:

ii  brdcp7030lpr:i386       2.0.2-1         Brother DCP-7030 LPR driver 

ii  cupswrapperdcp7030:i386       2.0.2-1         Brother DCP7030 CUPS wrapper driver

Finally type

sudo gedit /lib/udev/rules.d/40-libsane.rules

and at the following text right before this line (pretty far down at the bottom)

'# The following rule will disable USB autosuspend for the device'

Text to add:

# Brother scanners

ATTRS{idVendor}=="04f9", ENV{libsane_matched}="yes"

Restart the computer now and it should work.
