Anyone finding this post will have the same question: why is it so hard to create an imposed .pdf in InDesign? Is it due to license wars?

I know, there is a workaround via .ps and distiller, but this fails, since there is no flexible generic ppd available. If your home printer only prints A4, you are not able to create an A3 .pdf to print at a printshop. Insane.

Please, Adobe, bring (back) this functionality to create imposed .pdf's at any size with the Print Booklet function, even when no printer is available.
