Reply To: Printing Booklet Cover to Left Edge

I would make one Indesign document just for the Cover and have that as the first document in your book file.
Then when you print it it will be a spread.
You are setting the pagination correctly? If you are printing the document and then folding each spread yo have to make sure the correct pages face the correct pages.
Eg for a 16 page document printed double sided you will have Pages 16 and 1 on one side and 15 and 2 on the opposite side of the paper. So when you fold and collate them they will be in the correct order. The keep following this for page printed page. This is normally done with imposition software not in InDesign, there some scripts to do this.
If yo have a cover and then 8 sections all that will be staple bound you will have to impose the whole document correctly for it to work when it is folded trimmed and bound. Of course the imposition will be different if it is perfect bound in sections.
