Printing booklet odd / even pages only is greyed out
I'm trying to print a booklet, but I don't have a duplex printer. When I visit Adobe's guidelines, it says:
Printing double-sided pages without a duplex printer
Use the Odd Pages Only and Even Pages Only options in either Adobe Acrobat or InDesign. After one set is printed, flip over the pages, load it in the printer, and print the rest of the pages. For best results, print a test document to see which direction and order the pages should be added to the printer.
My problem is when I try to select the option to print odd or even pages, that section is greyed out. What am I doing wrong?
