I installed the Spyder3 Elite using Windows XP Service Pak 3. The monitor  
that was calibrated is a Samsung 21 inch LCD SyncMaster 2443BWX.
 
I took a known image and printed it using two different monitors. The  
images were placed on the same piece of Epson Lustre paper.
 
The two images do not match each other. One is much more green and the  
other is almost right on.
 
So, have i done something wrong. The images were printed using CS4 and I  
must admit confusion might have caused this. I do have a slight learning  
disability that hit me when I was 61.
 
I found the documentation lacking and had to "wing" it's first use. Where  
do I place the profile for the monitor? Does it go in   COLOR /  SETTINGS / 
WORKING SPACES and do I set the paper in the Epson Pre-print  Setup pages? 
or do I set the paper in CS4?
 
Thanks in advance
