One example of such type of implementation would be Mopria (and many others) Here's a example of such specification https://mopria.org/spec-download Mopria is nothing else than IPP with Bonjour discovery support. As a example, my printer can be used with USB. In this case, CUPS will detect it and suggest a driver (or use the generic driverless based on PDF/PCL/PS). If I choose network discovery when adding a new printer, I'll see many printer found (even if I got only one on the network). It will say "Internet Print Protocol (driverless)" with different options like PDF/PCL. I doubt that driver will really be gone as printer have specific options like the number of drawer, the precision (DPI) and much more. Often I've read "XYZ will have no place in the future" but still is being used today and has even grown. Driverless is somewhat a euphemism for generic. As a example, most USB mouse are considered *driverless* but the reality is more that they use the generic USB driver. Same goes for USB webcam that are sold as *driverless* but use the USB Video driver. > Hope this help If you want more information or a screenshot of the add printer screen on CUPS with the list of *driverless* printer found. Then I'll be glad to do my best to help you out. Don't hesitate. -- Polyna-Maude R.-Summerside -Be smart, Be wise, Support opensource development
