Re: "ipp-attribute-fidelity" and media selection

Smith,

I would ask the same question but I'm wondering what the answer is based on different workflow:

1. Client performs Validate-Job operation first. If the Validate-Job fails (due to fidelity = true), is it illegal for the client to send a Create-Job or Print-Job request anyway?

2. Client does not perform Validate-Job operation, and issues Create-Job or Print-Job directly.

I'm am certainly no expert on all the IPP specs (major understatement), and therefore am wondering if certain workflows are or should be defined?

Thanks,
Chris

Subject: [IPP] "ipp-attribute-fidelity" and media selection

Hi there,

(I should know the answer to this already but it seems I do not.)

If a Printer receives a Job Creation operation that includes "ipp-attribute-fidelity" = 'true' and also specifies "media" = 'na_letter_8.5x11in', but the Printer does not have that specific media size loaded, how is the Printer to respond?

Appendix C of RFC 8011 says "The Client is requesting that the Job be printed exactly as specified, and if that is not possible, then the Job MUST be rejected rather than processed incorrectly."

However, if the specified media size isn't loaded / available at Job Creation time, can the Printer accept the Job if it "promises" to honor the "ipp-attribute-fidelity" = 'true' Job Template attribute by keeping the new Job in the 'pending-held' state until the requested media size is loaded, or otherwise abort the Job? Is this also acceptable for the "ipp-attribute-fidelity" = 'true' case? This is not "rejecting the Job" strictly speaking. An aborted Job would show up in job accounting while a rejected Job Creation operation presumably would not.
