Is this on win7? Win7 doesn't seem to handle printer drivers very well in my opinion.
Try this:
Go to control panel, admin, services. Scroll down the list till you find 'print spooler' right click it and stop service.
Then go to C: drive>Windows>system32>spool>drivers folder. There should be a folder in here called w32x86, rename this folder to w32x86OLD.
Then go back to your printers and devices and remove the brother printer from the list.
Go back to admin services list and restart the print spooler service.
Now install the printer driver/software from your disk or install file.
That should do the trick. Good luck
Yes, win 7 that's been kicked in the nuts by malware. Will give that a go, thanks for the tip!
