    hi all

    Is it possible to install rendering plugins on currently installed windows printers. What I mean to say is suppose printers a,b and c have been installed on a users machine. Is it possible to insall a custom rendering plugin on all these printers so that the existing functionality isn't disturbed. Effectively I would like to insert my rendering plugin into the chain of rendering plugins if any installed by the existing printer driver installation. I am particularly intrested in the IPrintOemUni::ImageProcessing and IPrintOemUni::FilterGraphics methods. I donot want to modify any of the print data, I only want to collect some statistics like the RGB pixel count etc

    That said, any other alternative strategy to spy on print jobs is welcome. I am interested in collecting the RGB pixel count for every printjob

    Thanks/Sreejith

    You cannot install rendering plug-ins in the manner you describe. So that is
    definitely not the route for you to pursue. While there is no recommended
    way to achieve what you want, I suggest that you look at app hooking/shim
    techniques to get the info you want using SDK level functions.
