Experimental [Page 24] RFC 2565 IPP/1.0: Encoding and Transport April 19999. Appendix A: Protocol Examples9.1 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 are not supported or their values are not supported.

The printer supported the "copies" and "sides" attributes and their supplied values. The status code returned is ' successful-ok'.

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).

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).
