After installation, the printer will not print. The message appear in the print queue as spooling then go to Prining but nothing prints. There are no error messages. I have properly uninstalled and reinstalled this printer numerous times. This printer worked well under WinXP. Why doesnt this printer print ? Anyone have any ideas. The scanner and fax work ok, it will not print.

You don't say what driver package you have installed. If it's the default one from Windows 7 then you need to download the Windows 7 driver from the Brother website for full functionality. The default one from Windows 78 is an old driver and it is a minmal functionality driver. You can slect the appropiate version @ http://welcome.solutions.brother.com/bsc/public/us/us/en/dlf/download_top.html?reg=us&c=us&lang=en&prod=mfc7420_allPlease remember to click Mark as Answer on the post that helps you, and to click Unmark as Answer if a marked post does not actually answer your question.
