The Samsung driver should be installed only on the server. Having
filtering done twice is very strongly discouraged and is hell to
debug.

I do not follow this and cannot see how a USB cable between client and
server does anything.

Printing can only take place if the printer is connected by USB to the
client or shared over the network. Not sharing the printer connected to
the server seems counterproductive.

A shared server queue provides an AirPrint service and the queue is
suitable for a driverless printing system. CUPS should be able to query
the queue for its IPP attributes and construct a PPD.

This is a queue that has been set up locally on the client using the
Samsung driver. It is likely to bring havoc to printing. Delete the
queue. If you really want to set up a local queue, use the CUPS web
interface with the driverless or everywhere models, or do
lpadmin -p c410 -v ipp://SEC30CDA71CB48A.local:631/ipp/printer -E -m everywhere

This is the printer itself. It would be interesting to see what is given
for 'avahi-browse -rt _ipp._tcp'.

This is the queue you have set up with the Samsung driver on the server.
It is the queue you should be using to print to. A PDF is sent to the
server when printing from LibreOffice. If you have printed a PDF directly
from the server, there should be no problem with the LO one.

This complexity of output indicates a local queue set up with the
Samsung driver. As has been said - you really, really need to get rid
of it.

The given <Samsung_C410_Series_ppd> is a placeholder for the actual
name of the PPD. I suppose I could have worked out what it actually is.

The placeholder is intended to be filled by Samsung_C410_Series.ppd.
