7.5. How can I disable the Print functionality?

Here’s how to disable the print features:

Just add the following CSS code under the Custom CSS tab in your Manual Settings screen:

#topic-header a.print-page { display: none; } 
@media print { * { display: none; } }

Make sure to also check the “Include Custom CSS” checkbox.

The above CSS code:

1. hides the Print button on all pages of your manual.
2. when printing from the browser, the printed output is forced to be empty.
   

Please note that this is not 100% protection against printing. A smart techie can probably insert his own CSS and enable printing again.
But the above will definitely make it harder for the average user.
