Appendix A. Protocol Examples
A.1. Print-Job Request
The following is an example of a Print-Job request with "job-name", "copies", and "sides" specified. The "ipp-attribute-fidelity" attribute is set to 'true' so that the print request will fail if the "copies" or the "sides" attribute is not supported or their values are not supported.

A.2. Print-Job Response (Successful)
Here is an example of a successful Print-Job response to the previous
Print-Job request. The Printer supported the "copies" and "sides"
attributes and their supplied values. The status-code returned is
'successful-ok'.

A.3. Print-Job Response (Failure)
Here is an example of an unsuccessful Print-Job response to the
previous Print-Job request. It fails because, in this case, the
Printer does not support the "sides" attribute and because the value
'20' for the "copies" attribute is not supported. Therefore, no Job
is created, and neither a "job-id" nor a "job-uri" operation
attribute is returned. The error code returned is 'client-error-
attributes-or-values-not-supported' (0x040b).

A.4. Print-Job Response (Success with Attributes Ignored)
Here is an example of a successful Print-Job response to a Print-Job
request like the previous Print-Job request, except that the value of
"ipp-attribute-fidelity" is 'false'. The print request succeeds,
even though, in this case, the Printer supports neither the "sides"
attribute nor the value '20' for the "copies" attribute. Therefore,
a Job is created and both a "job-id" and a "job-uri" operation
attribute are returned. The unsupported attributes are also returned
in an Unsupported Attributes group. The error code returned is
'successful-ok-ignored-or-substituted-attributes' (0x0001).
