Your setup would appear to be:
1. The C410 is connected to a CUPS server via USB (but the connection
can also be via wireless).
2. The server has the Samsung ULD software installed and is
advertising
shared queues.
3. The buster client contacts the server over wireless and is running
cups-browsed.
Please post what you get with 'lpstat -l -e' from the client. You
should
be able to recognise your print queue from the output, so follow up
with
'lpoptions -p <print_queue>'.
Not quite. The network connection is wired. The C410 only connects
wirelessly using WPS, which I have disabled on the router.

The printer is defined on the server (TheLibrarian) twice - once as a
network printer and once as a USB printer. It's defined once on my
workstation as a network printer, so I can avoid going through the
server.

Very useful. As confirmation (or not) of an idea, let us have what
cupsfilter -p /etc/cups/ppd/<Samsung_C410_Series_ppd> -m printer/foo \
-e --list-filters /etc/nsswitch.conf
gives (as root). The line is broken for readability.
Reading over the above output, it struck me that my printer setup
wasn't quite what I thought it was, so I went back to basics, deleted
the queues on both my workstation and the server, downloaded and
installed the Samsung driver on both machines then put the print
queues back.
Now I seem to be able to print from the workstation to the server via
the USB connector.
I stopped sharing the network connected printer from the server since
that really made little sense. Unfortunately I still can't print
directly to the network connection. The job gets processed but I just
get an error message again.
I tried switching to the "driverless" driver but CUPS complained about
not being able to copy the PPD file. I noticed an "IPP Anywhere"
driver but that produced the same results as the normal driver.
The error I got on both print attempts (normal and IPP Anywhere) was:
SPL-C ERROR - Disconnected from host. Please check the connection and
try again.

SYSTEM : src/os_hook
LINE : 1981
VERSION : SPL-C 5.59.01 06-19-2013
This was printed by the printer instead of the output I sent.
The lpstat output is now:

I thought I'd figured it out - that the network printer shouldn't be
installed locally, because it's automagically discovered. I tested this
by deleting the local install of the network printer and, while it
disappears from the CUPS web interface, it still shows up in the list of
printers when I try to print a PDF from Okular. This seems somewhat
reasonable...
Unfortunately, printing to it does nothing. The output disappears into
the ether(net).
To be clear, the printer network connection is there. CUPs lists it
multiple times with its network address when I use the web interface to
find new printers. And I can ping its IP address.
I then fired up a Stretch VM and tried the same things. Under Stretch,
the printer doesn't show up except as the USB-shared printer from the
server. However, after installing the Samsung driver, it did show up
when I tried to find new printers from the CUPS web interface. I
installed it using the SEC30CDA71CB48A "address" and the normal C410
driver and was able to print successfully.
CUPS is apparently working differently in Buster than in Stretch in its
handling of network-attached printers.
Anyway, here's my current diagnostic output:

Changing the _ppd to .ppd removes the error messages. Instead I get no
output.
