Digital BW, The Print

I find that my prints are consistently darker than my screen.  I use a
Macbook Pro and an external 24" Dell monitor.  I have profiled the
monitor with a Xrite eyeone -2 and print on a 2400 using ABW.  The
prints are consistently darker than the screen even when I use basic
Epson papers (e.g., EEM).  I have CS3 set correctly to no color
management and selected the paper correctly. The monitor is connected
via a DVI cable.  The monitor does not have a contrast adjustment, but
I can adjust the brightness.  However, I assumed that the eyeone takes
care of that during the profiling process.  

The tonal rendition (shadows, highlights and midtones) looks ok to my
very amateur eye.  The only problem seems to be that the prints are
consistently darker than the monitor.  While I can increase brightness
using a curve before I print, that seems to defeat the whole idea of
profiling.

Any help appreciated.
