[TYPO3] Customizing templates

[tonix (Antonio Nati)]

Sorry for the question, I don't know if what I'm looking for can be done.

Is it possible to write a unique template to be used for the whole 
site, in which single parts of the template may be enabled/disabled 
using TSconfig of each page?

I want to add a print version of the page, but only in some selected 
pages. So those pages should enable both the "link to print version", 
and the availability of typeNum98 format.

I would love to avoid to make a separate template for each of these pages.

Thanks,

Tonino
