Disable print button in browser

[duanzq]

Normally we can disable "print" by set CSS mediarint properties, but I cannot find which CSS should be modified.
Anybody can help me to do this?

I got this work done.
I modified the file "tomcat/webapps/share/WEB-INF/classes/alfresco/templates/org/alfresco/document-detail.ftl"
Add the following line
———-
<@templateHeader>
   <@script type="text/javascript" src="${url.context}/res/modules/documentlibrary/doclib-actions.js" group="document-details"/>
   <@link rel="stylesheet" type="text/css" href="${url.context}/res/components/document-details/document-details-panel.css" group="document-details"/>
   <@templateHtmlEditorAssets />
   &lt;!– Disable Print –&gt;
    &lt;style type="text/css" media="print"&gt;
        BODY {display:none;visibility:hidden;}
  &lt;/style&gt;
