Abstract
Content files are isolated in a sandbox as a content isolation environment formed by a secondary user account. Printing is controlled by an agent via a staging file of a secure file type. The agent intercepts print requests (e.g. print start requests and print end requests) in a printing sub-system of an operating system in order to coordinate and securely control printing of the untrusted content file via the intermediate staging file.
