To install my network printer in 11.10, I ran "Printers," selected "add,"
pointed at the network, waited a few seconds and selected my printer. At no time
did I go to the Brother site to find a driver.
(The above is off the top of my head and by memory, so it might be a little
inaccurate, but you can get the gist of it: Start with "Printers," not your
browser.)
