Recommended way to manually add an undiscovered IPP printer in CUPS 3.x

Hi everyone,

I'm working on the COSMIC printer setup application for CUPS 3.x.

I have a question about driverless IPP printers that are not
automatically discovered, for example, when DNS-SD/mDNS is disabled.

What is the recommended way for a desktop printer setup application to
allow users to add such a printer manually?

I'm looking for the intended approach in the CUPS 3.x architecture.

Thanks,
