Correct. Note that for Qt 6, some of the print engines that were previously plugins were moved into the QtPrintSupport library directly, such as the macOS print engine, but the interface for enumerating these from Qt’s point of view is still as print engine “plugins”. The CUPS engine is a fully standalone plugin, so it’s a good basis for the CPDB work.
