Ok. I've read a ton of posts on this and have tried so many of the "correct" answers without any luck. I have a 6in x 6in book that I'm trying to have arranged for printing through the Print Booklet feature.
I don't have a printer installed and am using Adobe InDesign 2020 with the most recent updates.
In the Print Booklet Preview settings the book looks correct. When the ps file is loaded in Adobe Distiller to make it a pdf the resulting pdf is the wrong size. The landscape book is cropped into a portrait page.
I thought I could just change the page size in the Printer Settings but thats greyed out. Not sure what the fix is. I've read posts on this and followed multiple answers with no result.
This worked. I had the same problem on a Mac Pro...previews fine but then the ps file was vertical instead of horizontal. It's just a line of code you have to paste into a folder. Not sure why, but don't care...it was driving me bonkers and I appreciate the fix!
