This is the printer driver ONLY. Brother has yet again proven thier lack of constomer service focus. If anyone has the install CD that supports Win NT 4.0, can you ISO it and get in touch with me so we can swap? I'll get it on driverguide for other screwed consumers. ***INSTALLATION INSTRUCTIONS*** Download this file into its own folder on the desktop. Trust me on this. Run the file (double click on it) in the folder. If you fail to put it in its own folder, the executable file will poop all over your desktop leaving driver files all over the place. I learned that the hard way. This works, and it is directly from Brother.
