Here is what I'm trying to do: 
I have four single pages in InDesign. Each of them is 150x100mm small. Now I want to print them out, but it would be perfect to have all them on one sheet of paper. After hitting cmd+P there is the thumbnails option in InDesign – but this one changes the original sizes. I would like to keep the original size and print several pages on a single sheet of paper. How to do that? Is there a script for that?

Thanks a lot in advance. 

Best regards,
Serkan
