Hello:

The print popup page is the same as we view in back without styles...

I know that Print option calls to print Joomla system and it display the same as article page with stars, description, comments and more...

I want to make my own print option (or modify anything). I need display for print ONLY article title and description..., how I can?.

Is very difficult to make a Print button in each article in the list of category?.

Thanks!!.

I am not in my hosting environment at the moment but I remember seeing a file in the template with "print" in the name.. item_list_print.php or something.
Try modifying that file slightly and seeing if that affects how it prints... I haven't needed to be able to print but that is where I would start.
Hope it helps!
