Looking at the second pic....I almost always ID panels in this way- though, if there is room, I am likely to place the lable on the breaker itself. It's simply a better way, I believe. The breaker is identified even if the cover is removed, and the lable moves if you move the breaker. That $30 printer has come in very handy.

Now for the bad news....the local inspectors believe that you MUST use the provided "directory." So, I get to fill that out as well. Go figure.
