Here a comprehensive explanation of all those different,
separated, but related things in modern printing world:

https://wiki.debian.org/CUPSDriverlessPrinting

In particular it contains a section about "the GTK Print Dialog".

This article describes how things behave with Debian
so that there will be this or that differences
compared to how things behave with your Linux distribution
because things in modern printing world are moving
and under development.
