:)   Possibly not...

I don't think any of this changes the notion that the current

     "Output intended for: Printer"

wording is pretty unhelpful, and whatever the difference is between the 
options, it could be more clearly expressed.

If the difference is simply RGB vs CYMK workflow, and printers can 
require either, why not word the choices as

     "Screen / Web / RGB work flow"

and

     "CYMK work flow" ?

I'm not sure that the tool tip in its current form helps much either.

Typical ink jets may take RGB at the driver interface, but so are some 
reasonably chunky laser printers. Users of both generally know that the 
inks / toners are CYMK. This knowledge also renders the "true CYMK 
printer" wording really ambiguous.
