I found this link -- https://ubuntuforums.org/showthread.php?t=2256885 for doing what I need. I followed it and everything seems fine, but even though "Printers" recognizes both the USB and the wireless everything goes to the Print Que, but nothing prints out.
Here is the info from a --- dpkg -l | grep -i brother
fred@Lenovo-G780:~$ dpkg -l | grep -i brother

This statement:
For troubleshooting purposes, you can access CUPS server errors via the error log file at: /var/log/cups/error_log.
That directory is not present in my system.
So I tried to install CUPs and found this:
fred@Lenovo-G780:~$ sudo apt install cups

The tool will be downloaded into the default "Download" directory.
(The directory location varies depending on your Linux distribution.)
e.g. /home/(LoginName)/Download
Step2. Open a terminal window and go to the directory you downloaded the file to in the last step.
In reality the files had to located in /Download/Drivers and then following their instructions everything worked and automatically installed the printer also.
