get job list queue from printer memory

I know that my开发者_开发百科 network printer (big Konica Minolta) have own memory and storage there some info like printed jobs. It is possible to get from this memory this information? I try to use Win32_Printer or Win32_PrintJob but as I read it gets only jobs queue from Windows dialog box ...

Have You some idea how resolve my problem ?

You'd need the API/SDK specific to the printer:
