Before, we were calling nsDeviceContextSpecGTK::StartPrintJob within the gtk_enumerate_printers callback function as soon as we found the printer we wanted to print from. This was causing the GTK printing backend to get confused about what the capabilities of the selected printer were when running in the content process, due to https://bugzilla.gnome.org/show_bug.cgi?id=753041. This moves the call to StartPrintJob to the next tick of the event loop.
