Also I wanted to know if I could alternate the pages, the printer needs them to be like this:
Page1 - Page 80
Page 79 - Page 2
Page 3 - Page 78
Page 77 - Page 4
etc... Do I have to do this manually, it is about 42 spreads (84 pages) long.
You'd be a lot better off finding a printer who can do his job.
