Actually, it has nothing to do with those plugins.

The conversion to RGB is the last step before printing when you
already have a grayscale image in a gray working space. You convert to
RGB before printing to apply Paul's curves or use sliders so the
printer driver make use of the ink correctly.

Those "Convert to b/w" plugins are for converting a colour image to
gray scale. Which is the first step if you have a colour image to
start with.  I found channel mixer good enough for that purpose.
