If GTK+ print is not ready, then our goal should be to get it there. It
is after all one of the most widely used printing APIs in the free
software world, it hides the platform details, is portable and it is in
our software stack w/o introducing an extra dependency. And it is the
printing UI that our target users (Linux users that use a GTK+ based
desktop) are familiar with. That's a lot of good reasons to keep it. And
so far I got the impression that it's just some minor details that are

Oh, this works totally straight-forward with my printer. If I select
Landscape paper orientation, then it will rotate the printout for me. Of
course I don't have to feed it the paper in landscape orientation. I
wonder if there's something that should be done differently in the way
that GTK+ Print talks to your printer driver. This seems to be an issue
somewhere down the way to your printer.

We could of course add a UI for changing the image orientation with
regards to the paper orientation. But I am afraid that this will only
make things more complex. Another setting that you would have to deal
with. That means more chances to get it wrong.
