User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_5) AppleWebKit/601.6.17 (KHTML, like Gecko) Version/9.1.1 Safari/601.6.17 Steps to reproduce: 1. Open Firefox using icon on dock 2. Open any website with a report that needs to scroll right 3. Open print dialogue (command + P) 4. Press the Landscape Button 5. On the Scale field, enter a percentage lower than 100%. Preferably 50%-65% 6. Press Print Button Actual results: Print job does not scale. Expected results: Print job should be printed in the scale indicated in step 5 above.

I replicated issue with various users in the office except for one. This user has Firefox 47 and scale function with landscape works fine.

Can you provide a website URL to test (or a simple HTML document) and attach the print output, please.

Could this be a similar issue to bug 1303051?

Ariel, could you test with Firefox Developer Edition, it's probably fixed: https://www.mozilla.org/en-US/firefox/developer/all/

Quite likely, since I cannot reproduce in Nightly when printing from the parent process.

Sorry for the late response. I couldn't gain access to my Bugzilla account. Looks like the issue was fixed with version 49.
