A host computer which generates a print job subjected to printing by a printer stores a drawing command output from an application in a spool file via a graphic engine. A spool system, the graphic engine, and a job chasing function processing unit execute a chasing data generation process by using the drawing command. The spool system, the graphic engine, and a graphics control unit execute a print data generation process by using the same drawing command. At this time, the drawing command is read out and output so as to successively execute the chasing data generation process and print data generation process. With this configuration, there are provided a method of protecting leakage of information by which the contents of information can be reliably chased without requiring either a special application or a device having a special function and posing any restriction on the read or output path, and an information processing apparatus and driver program which implement the method.
