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.On Thu 13 Jun 2019 at 21:31:49 -0400, Gary Dale wrote:On 2019-06-13 5:06 a.m., Brian wrote:[...]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. $ Samsung_C410_Series permanent ipp://localhost/printers/Samsung_C410_Series dnssd://Samsung%20C410%20Series%20(SEC30CDA71CB48A)._printer._tcp.local/ Samsung_C410_Series_SEC30CDA71CB48A_ network none ipp://Samsung%20C410%20Series%20(SEC30CDA71CB48A)._ipp._tcp.local/ Samsung_C410_Series_TheLibrarian network none ipps://Samsung%20C410%20Series%20%40%20TheLibrarian._ipps._tcp.local/cups Samsung_C410_Series_TheLibrarian_3 permanent ipp://localhost/printers/Samsung_C410_Series_TheLibrarian_3 file:///dev/null The printer is defined on the server (TheLibrarian) twice - once as a network printer and once as a USB printer.

The line is broken for readability.
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.
