A lot of information about the inner workings of CUPS is available through the web interface, which CUPS will always support. It works with any browser (yes, even text-based ones). Just go to http://localhost:631/ for a start. There you find a link to locally available CUPS documentation in HTML and PDF if you are new to CUPS.
CUPS is accessible through other means than KDEPrint: commandline and browser are two native CUPS interfaces. The many commandline utilities add up to the most complete control you have on CUPS. The web interface is only a subset of all available configuration or control options.
This is also true for KDEPrint. Generally, as CUPS develops, most new features will first be implemented through the commandline. Be sure to check the latest versions of the man pages for CUPS to stay up-to-date with new features after you install a new version.
Depending on your update method for CUPS, your active configuration file might not have been re-placed by a new one; thus your new, more capable CUPS-daemon might not have been told by the old configuration file about the new features to use.
A complete list of available files and man pages should always be
in the CUPS Software Administrator Manual (http://localhost:631/sam.html#FILES.
In the Konqueror URL/location field, type
man:/lpadmin
and
man:/cupsd.conf
to find out about the most
important command and configuration file. You knew already about
Konqueror's nice abilities to show you the traditional UNIX® man
pages, didn't you? Read this. From there you find more interesting
hints and links to other man pages and documentation.
Here is a way to find out which CUPS related man pages there are on your system:
