I have two Brother printers I have been very happy with. Key for me is the ability to print duplex (double sided). Brother MFC-8840DN (multi-function, not made anymore) also faxes-scans-copies. Brother HL-4070CDW is a color printer but I almost never use colors for tax; those are limited to the net worth charts I do on request for some clients.
The one beef I have with the color printer is that, since it is "Energy Star rated" it shuts itself down after x minutes of inactivity. So if you just need a page or two the older, slower, machine is actually faster as it is ready to go. It doesn't need to wake up, have its coffee, and check its facebook page and email, all before printing your page.
