Till,

The status callback is called as needed, so you basically need to open the printer device, query, and set the supplies from the response.  Look at the "pcl_status" code in my hp-printer-app for a complete example:

    https://github.com/michaelrsweet/hp-printer-app

You don't need the "dummy" sample values I include in hp-printer-app (it is still mostly sample code, even if people are apparently using it :) - if you don't get a response, just don't set the supplies.
