No doubt about that. In fact, I'd go as far as to say that CUPS is the only=
=20
printing system we should support on Unix. This is my *personal* opinion.

The problem is that we're no longer Unix-only. Here's where problems arise.

I understand.

Now it does. And it doesn't accept PostScript.

Agreed, but it has to be done only where it makes sense.

If we provide a "print a PNG" feature, we have to provide it everywhere (or=
=20
come up with a really good and convincing reason why it doesn't work in=20
certain circumstances).=20

Which in turn means we must not depend on a CUPS feature only: it has to=20
be "emulated" in our printing system if the feature isn't available in the=
=20
backend.

Printing image formats is rather easy, because we have image loaders. We do=
n't=20
have a PostScript loader though: so implementing a light-weight equivalent=
=20
of "kprinter *.ps" is close to impossible. Enter, therefore, the heavy-weig=
ht=20
all-purpose document viewer.

I have no problems with providing "kprinter" in KDE Workspace: we can easil=
y=20
say we support CUPS only in the KDE Workspace (see above). And this is also=
=20
not a co-installability issue, because KDE Workspace 4 cannot be installed =
at=20
the same time as KDE 3's.

No. You're hijacking every single thread that has "print" mentioned to=20
reiterate again and again your arguments. We have understood them.

Now let's stick to the topic at hand: installing KDE 3 and 4 at the same ti=
