Re: Registration proposal for additional IPP Printer firmware related attributes[EXTERNAL]

Hi Uli,

With IPP System Service in the Cloud, a Printer can be notified that
firmware updates are available and safely fetch the updates.

Direct fetch from the manufacturer has all the security weaknesses that
caused us to deprecate Print-URI.

Cheers,
