I have a HP Z3200ps printer. It appears the print module in Lightroom CC (latest addition) has changed with regard to the Page Setup. Used to be there were a number of different options available in the pop up dialogue box. (Print in color, print grayscale, paper size, quality, orientation, color system, etc.) Now, there are two options, paper size, which evidently I can't save anymore, and quality/orientation of print. Anybody else have this new Page Setup dialogue box?
System I7 6900, lots of RAM, Nvidia Quadro P4000
The page setup button actually calls the printer driver interface provided by the manufacturer. Lightroom has no control over that. Everything on that screen is provided, in your case, by HP. I have a Canon printer. I just checked and the interface is exactly the same as it has always been. If you were to open the printer driver from any system control on your computer you would see the same interface. Lightroom or Adobe have no control over that.
