Color correction for printing won't work

[FotograafTom]

Hey,

I would like to do a color correction for printing.
Only as you can see in the photo it cannot be changed.
because it is highlighted in light gray.
Anyone?

Thnxs allot

Don’t even consider using the print driver to color correct: do this in Lightroom, perhaps on a Proof Copy (Virtual Copy).

Using your computer OS print driver for color correction is ABSOLUTLY WRONG

In Lightroom Classic, in the Print Module, in the Print Job panel, for Color Management, select Other, select an ICC profile specific to your printer and paper and if available ink stock.
