PDF looks fine but printing rotates landscape to portrait



I've made a few PDF files where the first 5 to 6 pages are portrait and the last page is landscape. On the computer, it seems to open fine, but when I print the document, my last page instead of printing landscape, always prints out portrait. Is there a setting off when I am making my pdf?


I'd assume this is am issue with the printing software settings or the printer driver settings.
Could you see if there is an "auto detect orientation" option in your printer or the printing application?
