This post is to let people know that the Brother HL-2270DW printer can be installed and works under linux. I am currently using the printer in wifi mode printing to it from Ubuntu 13.04. I have posted installation instructions for Ubuntu 12.04 and these instructions also work for Ubuntu 13.04. Here is the link to the installation instructions http://chadchenault.blogspot.com/2012/05/brother-hl-2270dw-printer-driver.html.
I hope you enjoy this printer as much as I have.
