Kenneth (OP), thank you for this question. I am in exactly the same boat. After Apple abandoned its Aperture users I went to LR. Hated it in general but liked its print capabilities okay. Now I'm a dedicated CO user but have had a hard time with its print features and how they interface with my Epson R2400.
However, I did do some testing with QTR, computer managed and printer managed settings and to be honest, for my B&W printing using Epson ABW gave me the best results. This is not what you'll hear most of the time and I'm using the standard Epson inks (not dedicated B&W sets or piezography). I also use a very narrow range of papers. So, while it might not be the ultimate set up I have made some very nice B&W prints this way. I'm not a pro, but I am pretty picky about my results. And, if, like me you want one stop shopping then play around in CO, trial and error and write down the workflow that works for you.
My biggest issue right now is formatting within CO. I simply cannot figure out how to get the image dimensions exactly right. It is either very counterintuitive or I'm missing something or it just isn't possible.
If I remember correctly, in LR you could adjust your image dimensions in the same way that you would use the crop tool. And if you wanted the proportions fixed you had that option, just like the crop too. There needs to be a better option in CO than fiddling with unfixed margin parameters or cell sizes for a single image.
Someone mentioned the Epson tool and I'm going to try that.
