Im using Lightroom CC,windows 10 and an Epson Printer with premium glossy paper and correct Inks.
A4 Prints are coming out Dark and incorrect colours whilst prints done in Windows photo viewer are OK.
Im not very technical when it comes to the subject of Colour management but the link above shows the problem.
Does the link show the color shift before/after the printing? If so, that's a big difference.
Could you please post a screenshot of Lightroom print module settings?
