For the best, most detailed and most recent information you should always refer to the original CUPS documentation. CUPS is, much like KDE in a rapid development process. There are constantly new features being added. New features might for times be only configurable by directly editing the configuration files. The KDEPrint GUI might not have caught up with CUPS development.
Just in case you want to look at the original configuration files of your CUPS system -- they are here:
These paths are based on the default installation. Your operating system may have installed them to a different prefix, for example, /usr/local/, but the hierarchy should still match that shown below.
The following links only work if your CUPS daemon is up and running. To access all the original CUPS documentation, go to:
Direct access to the CUPS Software Administrator Manual in HTML format.
Direct access to the CUPS Software Administrator Manual in PDF format.
The following links give you access to the same files (probably icons and grapphis will be missing) even if your CUPS daemon is not up and running. You need, however, CUPS installed on your system. (Some distributions might place the files somewhere else -- you're on your own then to find out where...) To access all the original CUPS documentation, go to:
This documentation is available even when the CUPS daemon is not installed, although you may find images and icons are missing when you view the HTML files.
As noted above, the hierarchy below should be intact, but your operating system may have installed CUPS to a different location.
There are a few WebSites and Newsgroups discussing CUPS (and Linux® Printing in General) and giving help to newbies at:
LinuxPrinting.org, the home of the Linuxprinting HOWTO and the Linux® Printer Database
And finally, there will be a WebSite for KDEPrint and related documentation, at http://kdeprint.sourceforge.net/
In the next section I will step you through most of the configuration options of KDEPrint with CUPS.
