Features / Usability

I would start with something like this in your custom module.

{DIV(class="d-none d-print-block")}
||__Page Name:__ |__Version: __
__ Last Author:__  |__ Last Mod. Date:__ 
__ Approved by:__  | __Approval Date:__ ||
{DIV}

I meant... it doesn't work to me. Ok the module is hidden on the page, but it doesn't show on printing.
Not sure if these errors coulb be useful to debug:
NOTICE (E_NOTICE): Undefined variable: approval
At line 1964 in lib/parser/parserlib.php
NOTICE (E_NOTICE): Trying to access array offset on value of type null
At line 1964 in lib/parser/parserlib.php
The d-none class will hide the content on screen.
The d-print-block will unhide the content on printing.
