I think you are referring to pagination. Default A4 PDF files are Page 1 2 Page 3 4 For example. Here Page 1 is always the cover what you need in your PDF output is Page 4 1 Page 2 3 Like wise On an 8 page PDF Page 8 1 Page 2 7 Page 6 3 Page 4 5 This means you can 'print' your two pages on an A3 page so that when you print on the other side of the A3 page, the two A4 Pages are correct. Also for this you ALWAYS need multiples of 4 pages So for 6 Pages you need Page Blank 1 Page 2 Blank Page 6 3 Page 4 5 You can have 'fold outs' that can remove the blank pages but then you need 3 A4 Pages together and you have some options i.e Page 5 6 1 Page 2 3 4 or Page 6 1 2 Page 3 4 5 and so on If you are NOT just photocopying and using Litho Printers, then it gets more complicated because they will often want to print on larger sheets and so the pagination means that some pages are printed 'upside down' so that when they fold all the sheets together it works. If you are curious (and have 5 minutes and a couple of pieces of A4) then take you A4 sheet, fold it into A5 (fold it along the long edge) now take that A5 and fold it once more along the long edge until you get to an A6 size. Now have that a6 in front of you with the closed edge at the top and to the left hand side so that it looks like a little book. Now simply number the pages 1, 2, 3, 4 .. 8 as if you were trying to read it (leave the closed edge on the top), now fold it all out and you can see how 8 Pages are 'printed' so that you only need one sheet of paper. The printer will then 'trim' the top off so you have two smaller sheet and staple (stitch) the two sheets together so you have your booklet. If you want to see what 16 Pages looks like, repeat the above for another A4 sheet and before you start numbering, put the second folder A4 sheet inside the first and THEN number 1 - 16 and fold it all out. You can see how the numbering works, what pagination the printer needs and which pages are printed upside down.
