Support a cleaner print template format #2
Description
Similar to this other issue:
The print template for the site needs to be cleaned up as necessary, to ensure that things print well.
One obvious thing is removing the bottom mobile bar from the print template. But we also want special content sections showing up appropriately, and so on.
If someone wants to print a content page, they should be able to just open the print dialog and do it instantly. Whatever needs to be done to support that should be done.
