I follow Eric's tutorial on my 4880 and get satisfactory B&W prints. Whether you would think they were satisfactory is another question. All of my prints are on matte paper and do not have the DR you would get on glossy paper. Also, I've not measured the linearity of the output.
The tutorial has a section on printing B&W from Lightroom, which I followed. It is not difficult, and, by saving a B&W preset, very easy to return to that configuration.
I hope this helps.
