Hi All,
This is my keeper file on the default printer.
Hope this helps someone else.

Exactly what purpose does the "server default" printer serve?
Is it even possible to send the CUPS server a print job with
no printer specified? AAAAHHHH!!!!!!
On my system I didn't have any printers defined, so to test things I
added my network printer which is an Epson ET3700.
Before I started, ~/.cups/lpoptions didn't exist and /etc/cups/lpoptions
was empty.
To add my printer I went into the cups interface, as I always do, in
firefox and under Administration I selected "Add Printer". That
displayed all the print devices cups could see, which included "Epson
ET3700 Series" and "Epson ET3700 Series Driverless" under "Network
Printers". I selected "Epson ET3700 Series Driverless, and then in the
Model selection on the next screen, I selected the "Driverless Driver"
rather than the "IPP Everywhere Driver", then clicked on "Add Printer".
After defining the printer I checked ~/.cups/lpoptions and it still did
not exist, and /etc/cups/lpoptions was still empty. Lpstat -p showed my
printer only and lpstat -d said there was no system default.
Going into KDE's system settings Printer interface shows the printer I
added in Cups with "Default Printer" not checked, and when I click on
"Configure" and look at the printer properties it shows me the settings
I set in cups as the default properties.
If I start Libreoffice Writer and look at file->Printer Properties it
shows two entries for my printer, one with "Double Sided Printing"
active, which I set in the default options in Cups, and one entry with
"Double Sided Printing" turned off, and unfortunately both printer
entries have the same name.
The double entry that Libreoffice Writer shows is similar to the issue I
get under Windows. Under windows when I install the Epson printer driver
and install my printer, the printer installation creates two printer
definitions, an Epson ET3700 "Local" and an Epson ET3700 Network, where
the "Local" entry has "Double Sided" printing active and the "Network"
entry has "Double Sided" printing turned off and Administrator Disabled
so that it can't be changed. Even though the printer is set up this way
the "Local" definition still outputs to the network printer anyway.

Steve
Hi Steve,
This is exactly what I was seeing.
I did not realize that
~/.cups/lpoptions, and
/etc/cups/lpoptions
had to be set outside the WebUI (https://127.0.0.1:631).
Confused the heck (not my "actual" word) out of me.
The WebUI's default is server only. For what use, I can not
fathom.
To see what the Server's default is, check /etc/cups/printers.conf
as root.
su root -c "less /etc/cups/printers.conf | grep -i DefaultPrinter"
<DefaultPrinter HLL2300D>
</DefaultPrinter>
I reported the problem over on CUPS:
CUPS UI (631) fails to update the default printer in /etc/cups/lpoptions
https://github.com/OpenPrinting/cups/issues/818
They explained the misunderstanding to me.
I did ask on the bug report if they would included some
declaration on the Web UI's page that this was the server's
default and not the local machine's default so that
it would be intuitive to those without developer's level
knowledge of the situation.
"..it is not intuitively obvious to the lay user. It
took me two years to figure it out. Would you consider
removing the confusion for lay people by adding some
wording to the Web UI to the affect that "This is
the service side default printer. For your local
computer, set the default printer with lpoptions:
lpoptions -d printer-name.
Okay, and I know I may be pushing it here, but it would
be capitol if you added a client side setting for
default printer to the Web UI too."
I have not heard back from them, but it has not been that
long yet.
