Hello,
A couple of questions, OS version, Capture One (C1) version, Printer driver and Firmware up to date, FlexTight: .fff or .TIFF?
Printing from C1 or Adobe: Photoshop, Lightroom? Have you tried printing from another application?
In C1 v11 and v12, there is a Proofing tool (icon looks like glasses)
"Proofing recipes
Capture One can also soft-proof the selected recipe, thereby revealing any scaling, compression, or sharpening artifacts on-screen prior to output. By adjusting the settings with the proof mode enabled, you can see the real-time effect on-screen of individual selections, such as the effect of down-sampling when resizing images for the Web.
Select the image variant in the browser that want you to proof the settings for.
Highlight the recipe (or create a new recipe) from the list in the Process Recipes dialog, located under the Output Tool tab.
Go the Process Recipe tool, and under the various tabs select the processing settings, including the image size, profile, and output sharpening, where applicable.
Click on the Show Recipe Proofing (glasses) icon in the main tool bar, or from the main menu, select View>Show Recipe Proofing.
All the recipe settings applied to the image variant will be visible on screen for evaluation."

One other thing:
disable OpenCL and try deleting the image core cache to rebuild the kernels needed for OpenCL as well. You can see the guide on how to do so here:
