I can't say I'm a fan of Brother devices, they always still seem to infuriate me and end up pretty useless under a modern linux with my mfc-9440cn. Their downloads never work on a recent os, or otherwise end up causing problems trying to use a bigger hammer than native installers.
If I need to print/scan with my brother mfc, I just do it under my windoze vm as the only thing that behaves entirely properly, of course.
I'd love to never print anything again as it's smearing colors and such too, but works at least as a network scanner when needed when using the windoze driver/app. Hopefully that pesky paper thing goes away sooner than later, maybe even save some trees.
