Refer: https://support.brother.com/g/b/downloadtop.aspx?c=us&lang=en&prod=hl2170w_all
Mac Setup, Get Binary from Site
IP address for installation is: 192.168.000.012
Web Interface is: http://192.168.0.12/printer/main.html

Brother has web portal at http://192.168.0.12 (admin / access)
The Brother site does has some installation instructions but it's for 32-bit software had to mess around with it, but the drivers seem to work, maybe? Still used the Printer wizard.
Here's the installation instructions and *.gz file:
linux-brprinter-installer-2.2.zip
Using the wizard from the command line is the best way to install. Choose option to install with IP address, when finishing and testing the installation.
Make sure you run the installation as sudo and also choose at the end "Will you specify the Device URI? [Y/n] ->y" with option 12 to specify the IP address of the printer as 192.168.0.12
