Oh, and as I was writing this up I thought of maybe the following as well (since IPP/1.1 is vague about what the history contains):
job-history-attributes-configured (1setOf keyword)
This Printer Description attribute lists the Job attributes that will be retained in the history phase of each Job. IPP/1.1 [STD92] specifies that at least the "job-id", "job-printer-uri", "job-state", and "job-state-reasons" attributes MUST be retained in the history phase.
This attribute MUST be supported if the "job-history-attributes-supported" (section N.M.P) attribute is supported.
job-history-attributes-supported (1setOf keyword)
This Printer Description attribute lists the Job attributes that can be retained in the history phase of each Job.
This attribute MUST be supported if the "job-history-attributes-configured" (section N.M.P) attribute is supported.
