So what to do now? On my android device, I installed a mopria app,

finds my brother laser printer just fine. But to print from my linux
desktop, I've never setup a system printer, just depended on printing to
google cloud via chrome.
From what info I found via google search, cups should just work with
mopria-
enabled printers (like mine). According to articles I found cups should
just
detect it as available network printers. So I tried it. kde printer
config
and system-config-printers both detect nothing as available network
printers.
Mopria app on my android detects it just fine. Both connected to same
wifi.
Debian has a decent document on CUPS Driverless Printing
<
https://wiki.debian.org/CUPSDriverlessPrinting#The_Concept_of_Driverless_...
Driverless printing was designed for mobile devices that might encounter
many different printers so could not afford the overhead of setting up
individual
printers. The compromise is to have a small set of capabilities that was
easy
for all the printer vendors to support. I have a Mopria certified
printer from
Canon that usually works with my wife's IOS devices, but on my desktop I
use
the CUPS/Gutenprint PPD for the Mopria printer. Some documents fail using
Mopria but do print from Fedora or Adobe Acrobat on Windows.
Any ideas how to debug this and/or fix it?
Does the printer appear using "avahi-browse -all | grep Printer"? Mine
shows
up as both "Internet Printer" and "UNIX Printer".
My Mopria-capable printer didn't appear using the Gnome tool in Fedora 31,
but CUPS Admin <
http://localhost:631/> gave me two options: Gutenprint and
another that didn't
use Gutenprint. I thought that might not provide the full capabilities so
went
with Gutenprint.
