After the latest security update for Windows 10, I haven't been able to print from Mozilla 49.0.1, i disabled the Adobe Flash protected mode but the problem persists also reinstalled Mozilla erased every previous printer profile but nothing seems to work I'm not experiencing this issue under any other browser. Unfortunately I use this functionality on a daily basis. Flash player is up to date 23.0.0.162.

I'm an employee of a software development company, we developed an app written in ActionScript 2  in order to print we use PrintJob.
