Hi!
Since I was able to build and run cups on the N900 (I provide
packages in the maemo repository) it is still not usable in apps
like abiword or leafpad, because libgtk+ is not build with cups
enabled. Some time ago, I rebuilt these libraries with cups
support, and printing with this applications worked well.
CSSU cannot provide cups support, but maybe they could
provide experimental libgtk+ packages with cups enabled in
extras.
So there would be no need to rebuild the libraries after CSSU
updated them.
It would be sad to drop printing support on the N900, because it
is so easy to implement.
