I am a Debian lover. I use Debian at home. But EasyDebian is not my
choice on the N900. I think, adding printing support directly to the device
is the better way.

I think, you should only install libgtk2.0, libgtk2.0-bin and libgtk2.0-common.
Leave the other packages as they are. They are only in the archive, because
I have build the whole gtk2.0 packages. On the other side, they should not
make any problems, because I did not modify anything else. I only recompiled
them. But now libcups2 is found and printing in gtk is enabled. Your install
problems must have an other reason. On my device I only installed the above
3 packages.
If there are no more problems with the cups packages, please vote! Maybe the
maintainer of gtk can rebuild the packages against libcups2. But before, they
must make it into testing or even stable. The things I did with gtk, leafpad and
abiword are only a workaround. Unexperienced users could scratch up their
whole installation, because libgtk2.0 is a very critical package. Nearly all
packages depend on it. Let's try to make it official!
