User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.11; rv:48.0) Gecko/20100101 Firefox/48.0 Build ID: 20160823121617 Steps to reproduce: Reset all printer settings via about:config AND deleted all printing preferences in .js file. I could only solve the problem by reverting to FF v48. I am using a Mac with El Capitan. Actual results: Nothing changed, FF only prints in portrait, only at 100% zoom and single page layout no matter what options are selected (even with resetting) as above. Expected results: Printing in landscape, printing at different zooms, etc.

Probably related to bug 1303051 and bug 1301765.

Could you download Firefox Developer Edition and confirm that's fixed, please. https://www.mozilla.org/en-US/firefox/developer/all/

I have now download the Developer version as requested and verify the problem no longer exists; all printing options and varieties are working. Thank you.

Ty.
