Please not that libgnomeprint/libgnomeprintui is quite outdated library 
and I wouldn't advise to take it as example. It's better to look on
new printing work for GTK, for example this thread:

There were other discussions during last month on usability-list and on 
gtk-devel list with new printing dialog mockups and so on.

Printing library is required for many applications but I don't see much
use of scanning functionality _inside_ AbiWord. Isn't it better to have
scanner app managed by remote (say dbus) interface that can produce
documents for later import of them. Of course this just requires design
decision. I would say it's better to have a managed app and the
advantage of an application is that you can make it's development
significantly faster by using modern language.

You can use free OSS hosting like or to start. If you
already have gnome-complaint application you may request bugzilla
product on, directory and some dir for
your project in gnome cvs. You can easily create new channel on and page on gnome wiki - is
also a good place to register your app. But it's really hard to be GNOME
application, you might want to look here

for the list of required functionality
