I thank you sincerely for getting back to me on this. I wanted to let you know I just figured it out! I thought I’d document it for the next person to come along.
I had tried all of the options in that screenshot, and none seemed to work.
Investigating further, it was a Brother printer, so I needed to download special drivers: https://support.brother.com/g/b/productsearch.aspx?c=us&lang=en&content=dl
Then, arcane magic needed to be performed on the command line: https://support.brother.com/g/b/downloadhowto.aspx?c=us&lang=en&prod=mfcj4335dw_us_eu&os=128&dlid=dlf006893_000&flang=4&type3=625
I had done all that, but I still had a problem. Digging through the script output, apparently I had a bad “libsane” installed with apt. Also, to add to the problems, apt doesn’t recognize the string “libsane” now. We are to use its new name “libsane1” now in apt! So, I tried to reinstall and then reinstall the brother printer drivers, to no avail. Eventually, I had to completely uninstall libsane, and then reinstall it. And everything magically worked.
It’s so easy! 🤨
One thing to be ready to have is the IP number of the printer, which I was able to get in the WiFi options of the printer.
Whew! Test page printed on my test machine! I feel like this was my last major hurdle before adopting Linux on other machines.
Again, thanks for responding!
I’ve heard “dub-dub-dub”. But yeah, saying the abbreviation is longer than the words it’s abbreviating! 😀
