Get a color calibration kit and use it to get the color profile for the printer and the paper types that you will be using.
There are a lot of things that you can print out where the color is a bit off or even deliberately tweaked and it won’t be a problem. Getting skin tones right is not one of those. When I was printing out pictures of my grandkids, the skin tones were just a little bit off but it was very noticeable. Twiddling the images and printer settings by hand never quite got things right. Always little too red or not quite enough red. Sometimes a bit green; sometimes a bit yellow.
After I got a color calibration kit and used it, the pictures turned out on the money every time.
