I had CUPs installed, but just cleaned it from my system.
I deleted all the printers from the Gnome panel.
Yet when I ask to select a printer, there are two queues/connections to the same physical printer (I have only one printer at home). Only the first queue/connection will print anything. The other one just sends the job to la-la land without complaint or notification.
How does my system even know about this printer after I purged CUPS from my system and deleted the remaining queues from Gnome panel, and why does it show two connections to it?
Also, what is that printer named "print" whose status is rejecting jobs? Where did it find that?

I have that exact same problem -- exactly as you show it in the screenshot. I have not attempted to delete/purge cups.
Using Ubuntu 18.04 LTS (minimal installation) I set up a brand new (out of the box) HP laserjet, got it up and running, and booted up my PC. And the printer was right there where I expected it to be. However I couldn't print a test page ("file corrupted" says the printer). A little investigation showed that the printer actually worked (I could print up docs with no problem.) Then I noticed the duplicate printer entries (I have only one printer) and I noticed the odd "print" printer that was "rejecting jobs."
I spend a couple of hours trying to figure it out, and didn't find any answers that I understood or thought would work.
But I did notice that when I switched OS to Ubuntu 19.x, that version of Ubuntu didn't exhibit the problem (it worked perfectly). So that's my answer:
switch to Ubuntu 19.x ("disco dingo.")
(I also have been wondering why Libreoffice Ubuntu 18.04 LTS can't access docs on a shared drive unless I mount the drive locally, but that's another question.)
