CAPS Printer Driver Configuration Directory

This directory provides Driver Feature Configuration INI files for some printer driver default settings if appropriate. If settings do not match a printer device requirement, they can be overwritten on a printer device specific base (refer CAPS Printer Device Parameter Directory).

Each printer driver installs here its own driver specific configuration INI file with its default settings (if any). Its file name is referenced in the Device Description INI file. This driver specific configuration INI file can be shared between all driver users (e.g. printing devices), because it's read-only.

Refer Setup the CAPS Driver Configuration Directory as well.
