Capture One and printing to Epson P600

I have an Epson P600 and it prints nice color photographs with the provided Epson software. On the other hand, I loaded some images into Capture One 21 on my MacOS machine, from my Fujifilm XT4 and did a minimum of messing around. I liked what I saw on screen.

I chose the Print option from Capture One, and selected my Printer, the paper, all the good stuff. What came out of my printer was pretty much junk. A vague resemblance to my image in terms of greenish gray, orangey globs, what was originally a northern river with blues, yellows and mountains...

So all in all, no success there. I don't feel like wasting more ink and paper, as obviously, one cannot just use Capture One to print. One clearly as to do more. What more do I have to do? I am a rookie with this software, so any hot tips most appreciated.
