Printer selection does not work on Windows 10 / Firefox 52

[carlobonamico]

While testing this sample application (http://plnkr.co/edit/Y6474P2xKhQxcbH4lJe7?p=preview), which

• lists the available printers
• allows for default printer selection ("Set as default" buttons)
• display active configuration ("Print Status" button)

I noticed that on Ubuntu 16.04 LTS / Firefox 52 and Windows 7 / Firefox 47 it works correctly. On Windows 10 / Firefox 52 the application seems to work correctly in the sense that it displays the newly selected default printer, but when starting to print (e.g. with Ctrl + P on the page) the print display still selects the previous default printer.

Documentation clearly states that void print();

Prints content of most recent browser window to currently selected printer with current settings like window.print method. The difference between window.print() and jsPrintSetup.print() is that window.print() prints using settings saved in user preferences, while jsPrintSetup.print() print with current printer settings stored in jsPrintSetup.

Thus pressing Ctrl+P shows you user preferences, not the jsPrintSetup preferences.

After looking at your code I see that you are using window.print(), you must use jsPrintSetup.print() or jsPrintSetup.printWindow() otherwise you can't use silentPrint and printer select and all the other options, window.print() is stock browser print dialog.
