Printer Monitoring

Hey,

I am writing a vb6 app which cycles through a list of the printers I have hooked up to the network. What I want is to be able for the application to check...
->Ink/Toner Levels
->Paper Status
->Printer Status

I already can get the printers queue, but the above tasks still hide from me.

Any idea's

(1) Depends on the printer - not all printers support this function and they may implement it differently
(2) and (3) use the GetPrinter API calls - see these articles
