Printing problem - Canon Imageprograf 1000

Hello,

I'm trying to print on a Canon Pro-1000 and having some problems. I'm pretty sure I'm missing something very obvious.

All prints come out very dark. I would say it is at least 1-2 stops darker. I can't seem to correct this. When I use Photoshop everything seems to work well, prints look good. I cannot get Capture One to talk to the Canon Pro-1000 properly.

System: MacOS Big Sur 11.5.2

Capture One 20 13.1.4.15.

Any advice gratefully accepted. Thanks.
