For black and white visual monitor calibrators are... more acceptable? less 
unacceptable? something like that... than for color work. But this is still 
predicated on using a CRT. You need to effectively set you blackpoint to avoid 
clipping blacks, set your whitepoint to avoid blowing out whites, and define a 
detailed gamma correction (which is why it was called Adobe Gamma in the first 
place). Adobe doesn't even recommend Adobe Gamma for LCDs, since they don't 
start with a smooth, gamma shaped response curve, that can be nudged to the 
preferreed gamma with a single point, visual correction. Instead they look rather 
like stock market graphs, and require a point-by-point correction curve to 
balance that out. So seeing a good representation of your nice smooth, 
curve-corrected black and white printer output requires nice, smooth, curve corrected 
monitor output... which is not something you are going to get on an LCD without, 
as Paul puts it, a Spyder or equivalent.
