It is largely the same as using the CUPS web interface for configuring printers, but has the advantage of being a native application rather than a web page. It appears in the Fedora menu under System -> Administration -> Printing.
As a result of using the CUPS API the tool is able to configure remote CUPS instances and is not limited to configuring CUPS on the local machine. The CUPS library providing the API uses HTTP and IPP to communicate with the CUPS server.
Enhancements:
- Several improvements for the new-printer wizard have been made, and assorted bugs have been fixed.
