Will it network with Apple iBook Pro, Windows 7 XP professional & Ubuntu 8.10 ????
You would be best looking for all of the info in the manufacturer's website, but I did find info.
The win7 and win8 drivers should be available through windows update.
If you have a recent version of cups installed in ubuntu it should work without issues.http://www.openprinting.org/printer/Brother/Brother-HL-2270DW
For osx someone documented their steps at http://sneakydogsoftware.com/blog/?p=58
