Please keep in mind I'm a bit sloppy AND cheap in my development processes, but what I do is save my HC-110 dil. B after using it once for regular film development. I then use this left-over developer one-shot to develop 8x10 paper negatives. I use a wide range of expired fiber and RC papers in-camera, so I can't offer any advice about that. I also don't worry too much about capacity since I am using everything one-shot as I go.
I scan and invert my paper negatives, though. If you are contact printing a paper negative onto another sheet of paper you might want more contrast than I am aiming for. As usual only your own tests will help you get the results you want, but I'm happy to offer what advice I can.
