What's a "Print Processor" under advanced printer

[Andy_25 0]

If I right-click on my printer, choose properties --> advanced --> Print Processor, I can choose between two different "print processors" (Lexmark Print Processor and Win Print), and 5 different "default datatypes" (Raw, Raw [FF appended], Raw [FF auto], NT EMF 1.003, and Text).

 

Could someone clarify what these mean? I'm still trying to reduce the CPU usage when printing and when I came across this, I wondered if it has anything to do with it.

 

By the way, I now have a further problem with my Lexmark 3200; black text is really bad quality (also black graphics). When I use the "clean print nozzles" option, in the "cleaning" page, the black bar "fades out" towards the end. (and yes, there's plenty of black ink left )

 

Thanks,
