Why label? Is this not taking a chance that the ink will compromise the coating...and even worse, applying a label which will peel over time?
As we are often told, the only safe marking is on the clear area near the hub. However, if the disc is labelled - whether with ink or an adhesive - then Steven's observations are valid.
It is not obvious to me that thermal printing has the issues Jerry has reported; if not, that may be a more practical solution. If thermal printing also damages (or risks damaging) the data quality, then a code written on the inner ring may be the only viable solution for archival storage on optical media.
