Maybe a silly thought, but: Since your model is MySQL output, maybe take a look at the MySQL source code and see how it's done there. There's actually a tour of the source code here: http://dev.mysql.com/doc/internals/en/guided-tour.html - which might help you find where that printing is done.
Just took a really quick look at the mysql client code (at http://bazaar.launchpad.net/~mysql/mysql-server/5.6/files/head:/client/) - and all I saw were printf statements. Doesn't look like any fancy libraries or tools are being used.
