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
ii hll2340dcupswrapper:i386 3.2.0-1 i386 Brother HL-L2340D CUPS wrapper driver

ii printer-driver-ptouch 1.4-1 amd64 printer driver Brother P-touch label printers
fred@Lenovo-G780:~$
Below shows that "Printers" knows about them
USB Printer
Wireless Printer
A popup appears and states "Document Printed" I can see the job flash briefly in the "Print Que", but the printer does not wake up and nothing prints.
I verified it is working by printing from another Windows computer. Also in FireFox I went to the printer address and printed a page.......
Warning, I am new at this, like about a month every once in a while.
My only thought is that the CUPS driver is not installed, working, etc.
Thanks, Fred
