Hi. I try to print booklet of 40 pages. Size A5. PDF file. I use Acrobat Reader and paper sheets size A4. Four pages per one paper sheet. For examle on face side of first sheet pages 40 and 1, on the other side of first sheet pages 2 and 39, and so on. Pages 1 - 20 are OK, but for some reason pages 21 -40 moved 5 mm to the left (to the middle of sheets).
