We should be using the current settings from the tab modal print preview doorhanger to populate the system dialog that opens when the user clicks "Print using System Dialog". After https://phabricator.services.mozilla.com/D87754 lands we'll mostly do this, but there are definitely some settings missing. We should audit for that at some point. One example, is that on Linux the "Print in color" option isn't copied over. That is presumably because [nsPrintDialogWidgetGTK::ImportSettings](https://searchfox.org/mozilla-central/rev/19c23d725f27d0989e4a60f36d64004cebb39736/widget/gtk/nsPrintDialogGTK.cpp#367) doesn't check for and set that.
