Digital BW, The Print

I did some experimenting last night and found that in order to match 
my monitor I needed to use Gamma 1.8 (maybe even 1.5) when printing BO 
and Gamma 2.2 when printing full ink.  The Gamma settings are the ones 
in the Advanced options on the printer properties (R220).  All the 
prints were made on EEM so there isn't anything in the paper that 
would have made a difference. 

Is this something that is common or does it mean something that I'm 
not aware of?

Thanks!!  Brian
