Print and Export Security can be used to allow a user to run a report but not be able to print or export the report. Print and Export Security works at the individual report level. In order to use this feature, Report Level Viewing Security must be on in System Setup and Configuration.
To take away a user's ability to print or export a report you must make an entry for each report and user that you wish to restrict. The default is all users have the ability to print and export. Only those who are to be restricted need to be entered into the list of restricted reports.
There is also the option to have print and export security for every report by using the Global setting on the System Setup and Configuration page.
