I select "flip over" and instead, it prints the pages "flip up". I selected "flip over" in Printing Preferences and then selected "ok". However, when I open Printing Preferences again, before printing, "flip up" is selected as though I hadn't just chosen the other option. Any thoughts? I am printing a landscape 8.5" x 11" booklet if that makes a difference.
Pager flip is controlled by the printer driver, not a setting in ID. That said, ID doesn't always communicate well with some printer drivers, so try exporting a PDF and print from Acrobat or Reader.
I ended up solving it by creating a Postscript file just before reading this. But thanks for your help!
