Abstract
Print operations are monitored and a DLP policy is applied, independently of the print interface technology used by applications that initiate print operations. A DLP component monitors for and detects print drivers being loaded into the print spooler. When a print driver is loaded, the print spooler creates a corresponding driver object, which is intercepted. The instantiated driver object creates multiple device objects to carry out various print functions. The device object print functions of interest are intercepted. Attempts to send text to the printer at a print driver level by intercepted device object functions are monitored, and application level context information is identified, such as the associated 0user. The DLP policy is applied to monitored attempts to send text to the printer at the print driver level, taking into account application level context information and the specific text of the monitored attempt.
