ABSTRACT:
A method and system for incorporating additional indicia into a document generated by an off-the-shelf computer application without altering the source document or the application. A source document created by an application is sent to a printer driver for creation of a document image from the source document and delivery of the document image to a printer. Execution of the printer driver is interrupted, preferably after each individual page has been sent to the printer driver, and program flow is redirected to a sub-application. The sub-application is a program that monitors the stream of commands to the printer driver and takes actions based on a selected set of those commands to modify the image that is being prepared for printing. The exact nature of the modification would be dependent on the desired result for the sub-application but most likely it would be an operation that would render indicia onto the document image in addition to any that the application had already placed there. Program flow is then redirected back to said printer driver.
