My printers.conf contains a short list of printers. When I open the Print menu of any application, a longer list of printers is shown. Besides those from printers.conf, there are some more from our corporate network. Through which mechanism does CUPS find those printers, which configuration files and parameters control this behavior, and how to switch it off?

My PC is fully administered by myself; it's running plain Debian. So the printer list is not pushed by the corporate IT. Rather my PC has retrieved this list from the network - against my intent, by some hidden mechanism.

For some reason cups-browsed was installed. I stopped the services cups and cups-browsed, uninstalled the package cups-browsed, rebooted, and found clean print menus as defined by /etc/cups/printers.conf.

Clues came from @waltinator and from How do I disable automatic remote printer installation?.
