With the Macbook and the CD I have set up your printer and shared on the network. (In the router I had to adjust the allowed to communicate the devices to each other)
On each device, I had the printer only looking for short and then printing already went.
I tested it. With Win 7 Notebook and Macbook via WLAN
And with a PC connected via LAN to the router.
On the Android phone I had to install the Brother app, then printing was thus.
Printing via WLAN works through with me by a number of thick walls.
The print quality is good, I use it, however, primarily be filed to things, so I have not so demanding.
The only disadvantage of the printer is quite noisy, even if it does not print.
As it stands but with me in another room does not bother me that.
Overall, strong buy recommendation!
