Digital BW, The Print

It seems to me that printing in a Mac with QuadTone RIP, starting from Print with Preview 
in Photpshop CS, there is one additional selection to take care of.  The first window that 
opens up, calls for a profile definition, on the paper being used with the printer.  How 
does this interfere with the two curves on the QTR window?  In the next window, what 
media type should be selected?  It seems to me that the Help menu is missing for Mac.  
Can anybody help me please.
