Digital BW, The Print

Can anyone tell me how to install a second QUAD printer in QTR 2.1d?  I've 
tried adding one in the Printer Setup Utility and running the curves install, but 
the curves don't seem to install in that new printer.  Using the installer script 
doesn't load a second QUAD printer either.

The Epson 2200 I installed in Printer Setup Utility works fine.  I just can't figure 
out how to get the second QUAD printer to work.

I'm trying to avoid the trash/install procedure each time I change from MK to PK 
and to colour.

TIA,

peter
