Yes, had a look into this. But was not sure about it.
In general I can place a profile under /usr/share/cups/profiles/ - But I 
understand that this is used for all Cups devices.

If I want the profile only in one printer, I need to modify the .ppd file for 
it, correct?
So I copied the ppd with a new name, and added a line 

*%=== Color Management ================================
*cupsICCProfile ../Default: "/etc/cups/profile/
BrotherMFC9340CDW_Kopierpapier.icm"

When printing a test page from GIMP, I get the tree option
Color Mode = none / normal / vivid

should I use 'none', as color mode is now managed by the profile?

Thanks
