Using the softproof icc profiles to print in Lightroom

On the other Piezo site, i was reading that one can use an “icc profile” to print via LR with the Pro Inks. So, do i understand correctly that I can just use the icc profile that I am using for soft proofing, point to this in the appropriate LR dialog box on the Print menu, and obtain the appropriate mix of inks? This seems too good to be true. What am i missing?

These ICCs work for printing from Lightroom. Lightroom requires “industry standard” ICCs. The SoftProof ones are not that.
