[IPP] RFC: job-history-interval-configured/-supported Printer Description attributes[EXTERNAL]

Ours do keep jobs in history until they scroll of the screen if you will. Weeks even months. However if you send hundreds of 1 pagers, they drop off quickly. 60 seconds sounds like a good default for the print controller to keep track of them

Hi,

I hope Job Extensions, because I see them as filling holes in original IPP/1.1.
All printers implement some Job History (perhaps pretty short-lived).

Cheers,

+1 for all 3 of them.

To what spec do we want to add these? Job Extensions v1.1? Enterprise Printing Extensions? Or System Service?

Hi Mike,

Yes, to all three of these proposed attributes.

Cheers,

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.

All,

For your consideration, the following two Printer Description attributes would allow a Client to discover (and potentially the administrator to configure since the values are settable) how long a Job will stay in the history phase.

(I also considered "job-history-xxx" and "job-history-time-xxx" for the names; "interval" seemed the most consistent with other existing attributes, particularly with notifications)

--------

job-history-interval-configured (integer(0:MAX))

This Printer Description attribute specifies the minimum number of seconds that a Job will remain in the history phase of its lifecycle [STD92]. Printers SHOULD have a default configured value of at least 60 seconds to allow Clients to discover the disposition of any Jobs that have reached a terminating state.

This attribute MUST be supported if the "job-history-interval-supported" (section N.M.P) attribute is supported.

job-history-interval-supported (rangeOfInteger(0:MAX))

This Printer Description attribute specifies the range of values that are supported for the "job-history-interval-configured" Printer Description attribute.

This attribute MUST be supported if the "job-history-interval-configured" (section N.M.P) attribute is supported.
