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

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

Smith,

I mostly like and will copy this into the IPP deck.  As for terminology I'm leaning towards:

- Client-supplied: Client gets firmware updates and uploads to the Printer/System
- Client-initiated: Client tells Printer/System to perform an update
- Autonomous: Printer/System autonomously checks and updates firmware from a trusted source

Thoughts?

I'll see if I can articulate all of those from this thread in a draft registration document that I'll post before the F2F? Or should it just be slides, since there's been discussion of adding different sets of updates to System Service and INFRA?

The cloud service is then responsible for performing the tasks for that printer. This is a fully authenticated, encrypted process. Zero trust and everything. I just left out the details of our particular solution.

The "printer-firmware-update-version" and "printer-firmware-update-string-version" are intended to fill that gap. Mike suggested that we might define a new operation to cause the printer to fetch and update itself, and I think that is something we ought to investigate or at least discuss. This would compliment the existing facilities in System Service, and from a user experience and implementation perspective it would be easier for a Client to support this type of firmware update flow than the existing System Service supported process where it would need to download the firmware image / file to itself and then submit  it to the printer. I think the existing System Service flow is likely more desirable for larger / enterprise deployments where a fleet might be upgraded using a common firmware image.
