Description

8 months ago
User Agent: Mozilla/5.0 (X11; Ubuntu; Linux i686; rv:53.0) Gecko/20100101 Firefox/53.0
Build ID: 20170509210301

Steps to reproduce:

I printed several pages from Firefox.


Actual results:

First time the print was double sided, next prints were single sided.
After making a print from Firefox, the preference print.print_duplex is
created in prefs.js with a value of 0.
After a first (double-sided) print, this preference is created. The
result is the next print is single side.


Expected results:

The prints should be double sided (set by the printer) all times. Firefox should not overrule the printer settings.
