Hi, your PDF reader should have an option to print as a booklet. Use the “singles” PDF. It’s a little tricky to get right, so might take a little trial and error.
Thanks, I sorted it out, the reader I was using didn't have a good print option and didn't recognise my printers double side printing, i switched to Adobe reader and all was good. For those that want to know .... to print a double sided card stock cover, print in "booklet" and print the "page range" 1,2,23,24
