GNOME (GNU Network Object Model Environment) is a user-friendly set of
applications and desktop tools to be used in conjunction with a window
manager for the X Window System. The gnome-print-devel package
includes the libraries and include files needed for developing
applications that use the GNOME printing capabilities.
You should install the gnome-print-devel package if you would like to
develop GNOME applications that will use the GNOME print capabilities.
You do not need to install the gnome-print-devel package if you just
want to use the GNOME desktop environment.
