Why not just put this in settings?

You didn't address this comment.

Sorry about that - I somehow seemed to have missed this file.

The reason I didn't put this in settings is because the settings param contains
a lot of printer related settings that is then sent all over, and used to get
the appropriate printer settings.  The header footer strings are not printer
related and will not be used by it - thus - I created a separate parameter.
