Abstract: Techniques are described for auditing print content during printer redirection in a virtual desktop. The ability to audit redirected print content allows an organization to pre-define certain sensitive data and to track whether print redirection requests in the virtual desktop environment contain any such sensitive data. If such sensitive data is contained in a printer redirection request, a file is generated containing information about the sensitive data, as well as a watermark that encodes information about the printer redirection request, such the user identifier of the user who initiated the print request and a timestamp of when the print request occurred. The generated file is transmitted to one or more registered recipients.
