All,
Continuing the discussion from the minutes of the November F2F:
- Q: Should we list recommended attributes?
- job-password-repertoire-supported, jpeg-features-supported, some others
- Would also make sense for IPP Privacy Attributes
- A: Continue discussion on the mailing list, get closure on final list to add
- Could also reference/recommend additional specs that could be used in addition to IPP Everywhere for specific functionality:
- IPP Transaction-Based Printing - enterprise/managed printing
- IPP Shared Infrastructure Extensions - cloud printing
Looking at the current set of specs and registrations, it seems like there is nothing to add for the Shared Infrastructure Extensions - a Cloud implementation would look the same as a local one to a Client.
Aside from the Transaction-Based Printing extensions attributes, we can include the IPP Privacy Attributes and job-presets-supported from IPP Job Presets.
We could also add the Get-User-Printer-Attributes operation from the IPP GUPA registration but I am not aware of any implementations (yet)...
