So you are proposing that 'ink settings' are one of the printer setup
characteristics that exist in a workflow data container, and then also can
be pulled into a profile as it is built using the particular ink settings.

How about a function that supports "selectively initialize the printer setup
for this new profile - including ink settings -- from this x existing
profile"?
