the location of this new extra printer icon button can be done via JS, I suppose, although I have not found the solution so far ...
but I have the following more difficult issue:>> When a final user opens a pdf document in Internet Explorer 11, he sees the Aobe add on tool bar see below
to save,print document, enlarge / shrink or open adobe. Now I would to add the new print button to this Adobe Reader Add-on tool bar... Is thispossible, this solution would be great ... thanks in advance.
No, you can't set the location of the toolbar icon, and no, you can't add new tools to this floating bar in the Reader plugin.
