with whatever Job processing attributes, the IPP Client could query to see<br></div>how well the *attempt* would actually succeed (i.e., the extent of override<br></div><div>support for that specific document format).<br>

<br></div>This reply is about the usability of 'attempted'.<br><br>An IPP Client could use Validate-Job with "document-format" and "pdl-override" and,<br>when it receives the response that says ignored or substituted, examine the values <br>

<div><br></div></div>Well, if a Client sends "ipp-attribute-fidelity" (not "pdl-override"), then Validate-Job needs to respond just like Create-Job/Print-Job/Print-URI. So in that case "preferred-attributes" doesn't enter into the picture.</div>
<div><br></div><div>Instead, the Client would need to *omit* "ipp-attribute-fidelity" to see which overrides are supported. Then you'll get the unsupported attributes/values and potentially the ones that would be used instead.</div>
<div><br></div><div>Based on my own experience, I'm not sure how useful/reliable this method would be, but we can certainly document it.</div><div class=""><div><br></div><div>
