This is a small tutorial to make the printer Brother HL 2170w work on Arch. If you previously tried to install the printer in CUPS, remove it.
This printer will work a few different ways; with the HP PCL6 Driver, or with cupswrapper.
For further info on cupswrapper please see the Brother_MFC-440CN guide.
