How to disable print and copy access , I want to to provide only preview access to users

If I remember well in the new logicaldoc 6.0 there is a new privilege on folder called download.
You can leave the read permissions for the folder and disable permission to download,
so you will be able to see the folder, the preview of the documents but not to download them.

I able to restrict th euser to preview the doc but user can right click and take print of tha page and save the page .I need to disable the right click on preview mentioned below. it can restrict the user to print the page or save the page
