I have an Epson Surecolor P600 and an XP-820. Both giving the same problem. My PC is Windows 10 and I am using the latest versions of Epson drivers. The problem is a magenta cast on photo prints from Adobe LightroomCC and PhotoshopCC (latest versions today 5 Nov 2017) when I switch printer colour management off to use non epson photo paper. Searching forums I see a multitude of people with the same problem and uncertainty if the issue is with Adobe, Epson or my computer configuration. It seems that the general feeling is that even though I have turned off colour management, there is still management getting in the way, adding to the adobe management.
Printing is fine if the printer manages colour but I want to use non epson paper so want to have Adobe manage colour. I have a second computer running Lightroom and Photoshop and curiously on this system Photoshop prints OK but lightroom does not. I consider myself extremely PC literate and have read and tried all the forum posts I can find, nothing seems to work
