Supplementary properties/settings for [removed]win

Question

I would like tot give my Print this Page button a special magical property sothat it automatically enabled the by default unset property (see picture) namely to Do Print the Backgrounds of div colors and bg images etc.

<a href="#" onclick="javascript:window.print()"><? echo __('Print'); ?></a>

Clues, ideas, code, answers or suggestions as answers are all tremmendously welcome and I a will appreciate any hints at all for this dream to come true. Thanks in advance.

Answer 1

This cannot be done, unfortunately. This is disabled across all browsers by default (unless a user changes it in their settings).

Answer 2

This is not possible . You cannot change the browser settings , if that would be possible people could hack in very easily
