Reading the 1-star reviews at Amazon on the MFC-7840DW (the 7840W is no longer available), I see a common complaint about all the different Brother All-In-One models: Setting up wireless is difficult, and about twice a week it will lose its wireless connection and you have to do a complete reinstall of the wireless setup.

Also, this particular model does not seem to be Macintosh friendly, lacking USB drivers and having other Apple compatibility problems.

And nobody seems pleased with Brother's technical support, hours-long wait times and generally unable to solve problems.

I'll talk to my friend some more and see if she really needs all those functions. Maybe just a printer and a standalone fax machine is all she needs. That would make things a lot easier.
