Description:

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. GNOME is similar in purpose and scope to CDE and KDE,
but GNOME is based completely on free software. The gnome-print-devel package
includes the libraries and include files that you will need when developing
applications that use the GNOME printing facilities.

You should install the gnome-print-devel package if you would like to develop
GNOME applications that will use the GNOME printing facilities. You don't need
to install the gnome-print-devel package if you just want to use the GNOME
desktop enviornment.
