I print in a fully, end-to-end color managed environment printing on Epson SC800 printer.
Updated to latest Ps version. I am finding massive loss of color gamut when soft proffing and actual printing. Print made beautifully 10 years ago and 2 month ago now are coming out MUD. I can see the massive loss of gamut in the Print dialogue.
you need to be sure you have a good ICC profile for ink and paper,
I recommend using Photoshop Manages Color and do set the media type correctly in the printer settings options
