Hello,
RFC 2911 Section 4.2 "Job Template Attributes" includes the statement "An attribute "xxx" may be supported for some document formats and not supported for other document formats". If there is an interest in presenting UI corresponding to different attributes, and some were not supported by a particular document format, the code presenting the UI would likely want to not present or disable the UI elements for those that are not supported so that the user's expectations are not violated. What IPP operation or operations should a client use to query the IPP server to discover what attributes are supported for a particular document format on a particular Printer Object?
Thanks for any help,
Smith
