I appreciate the info about the new driver and such, but the original issue is that we can not choose Xerox Features from the driver in Safari, and that is still the case. Yes there is a workaround by making a PDF as an intermediary step, but there is still no solution to this problem.
Can you provide more insight as to what is happening in June 2018 that "should" make this work again? And that is still 5 months away.
