Version: (using KDE 4.0.1) As there is no kdeprint i'm not sure if this is the correct place. I think many would benefit from the ability to print multiple pages of a pdf (or any doc type for that matter) to a single sheet of paper. Personally Kpdf was far too limited with 4, and okular only prints single sheets!! :( Printing 6, 9, or 12 presentation slides on a single sheet of paper would be fantastic.
For now we are forced to use the Qt printing facilities; if they do not allow that, we cannot do much for that, sorry. Waiting for eventually better solutions.
Cups n-up printing is on my feature plan for KDE 4.1, either supported directly by Qt 4.4 (final features still to be confirmed), or by adding it ourselves to the QPrintDialog. Feel free to assign wish to me, and/or to come after me if it doesn't make 4.1 :-)
