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.

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.
I am interested in collecting the RGB pixel count for every printjob.
