I bought this printer (Brother HL-2270DW) last week to replace an inkjet MFP .
I am not looking back.
To those who have had problems installing this printer on their wireless network, I hope I can provide some assistance.
I had very little problems doing the install. (i'll explain the very little problems).
First, my hardware.
Airport Extreme 2009 edition (7.6.1)
MacBook Pro 17' 2009 late (10.7.4)
MacBook Air 11' 2011 late (10.7.4)
Brother HL-2270DW (Firmware 1.15 *****very important*****)
Before we start --- update all firmware - including firmware of printer which can be downloaded from the Brother website (

Step 1. Connecting printer to network
The Airport Extreme has protected network setup.
How do you access this feature? Unfortunately Airport Utility 6+ does not allow you to access these features, you need to download Airport Utility 5.6 from Apples website (
http://support.apple.com/kb/DL1482)
Once downloaded, start Airport Utility 5.6 and click on "Manual Setup".
Next, take your eyes and look at the very top of your screen.
You will see:
Apple Logo

apple

: Airport Utility 5.6:File:Edit:Base Station:Settings: Window:Help
Click on "Base Station"
then
Click on "Add Wireless Clients..."
Make sure Allow client by: Pin is selected.
(do not click continue yet)
Got to your Brother HL-2270DW printer. Make sure it's on. On the back of the printer you will see two buttons that can be depressed with a paper clip below the ethernet and USB connections. Depress the one at the very bottom with a paper clip for 5 secs and then release.
The printer lights will flash and remain on indicating that it's ready to pair with a wireless network.
Go quickly back to your computer (my laptop was actually right beside the printer) and click "Continue".
The printer took 30 seconds to print out an 8 digit PIN number. Enter the PIN number that was printeed on your printer into your computer and voilla! Your connected. But we aren't done yet.
**if your printer did not print the 8 digit pin after 30 seconds, depress the "Go" button your printer 5 times to get it to print****
** I did not need to do this, but I read it on the Amazon.com feedback comments for the printer**
****So the little problem I had was that I was using the "First Attempt" setup in the Airport Extreme wireless protected setup. For some unknown reason - the printer wouldn't see the network******
Step 2. 10.7.4 Brother Hl-2270DW Drivers
Go back to the Brother HL-2270DW official website and download the 10.7.4 CUPS drivers
(

Install them.
*I did a Disk Utility Repair Permissions before and after driver installation*
Here is where things get weird.
The MacBook Air - I had to restart
The MacBook Pro - I could proceed directly to installing the printer through "System Preferences", "Print & Scan" then "+" under printers and select the Brother HL-2270DW on the list.
That's it - now your done. I made it my default printer, I even created a profile to use less ink for jobs that I don't really need high quality.
If you need more help, just post your :
Hardware
Software
Firmware versions for all hardware
and the problem your having.
Hopes this helps someone have a quick and easy setup.
