My problem is that I nowhere find how to SAVE a 200x200 booklet from 8 pages on a A3.

I already know that you need to save it to a postscript file.

The thing is I dont have a A3 printer at home so I can't set it to A3. I also dont want to scale it because then it is smaller. It has to be the orginal size.

Anyone on this world who knows how I do this. It would be very helpfull.
