The network printer component of the MFC-7820N is easy in leopard– it’s detected by the mDNS (bonjour), and the drivers are preinstalled. Everything there should be smooth sailing.

However, we wanted this printer partly because it’s a network scanner, as well. Getting the network scanner component working under Leopard turned out to have a slight trick.

First, install the drivers:

  1. Go to the brother download site
  2. choose Drivers -> Mac OS/X 10.5 -> English then hit submit
  3. Install this driver, it’s the scanner TWAIN driver. It’s universal too
  4. This driver will make you reboot. Whee.
  5. Go back to the download site, and this time, do Utilities -> Mac OS/X 10.5 -> English
  6. Install the provided “Remote Setup Software”

Now, here’s the fun trick. Open your hard drive, and go to the folder /Library/Printers/Brother/Utilities/DeviceSelector. In this dir is a program called DeviceSelector . Run it.

Tell the DeviceSelector (and the scanner driver) to “Specify your machine by address”, and enter the IP address of your printer. (Mine was preset to specify by ‘name’, which is using mDNS).

From there, I could now scan through the control center applet or in a standard Twain app, like Image Capture in the /Applications folder.
