All CAPS universe components including the printer drivers use a specific set of INI files for their run-time configuration. More than one of such INI file sets do exist.

It depends on the type of the CAPS universe component which set it uses.

The following sets not only mention the specific INI files, they show the read-in order as well. This order is important, because latter INI files can overwrite settings already made by former INI files.

‍Example: If you increase the verbosity in the base caps.ini, all CAPS universe components become more verbose.
If you increase the verbosity in a latter INI file, only some CAPS universe components become more verbose. Refer CAPS universe verbosity setup via INI File for details.
