The new current text for the Create-Job operation is:
This operation is similar to the Print-Job operation (section 3.2.1) except
that a client supplies no document data or any reference to document data in
the Create-Job request. This operation is followed by one or more
Send-Document or Send-URI operations. If a Printer object supports the
Create-Job operation, it MUST also support either the Send-Document
operation or the Send-URI operation or both. Since a client can query the
Printer's "operations-supported" attribute, a client SHOULD NOT attempt to
use an unsupported optional operation.
I think that if the Print-Job operation is supported, then the Send-Document
operation MUST be supported, but the Send-URI is still OPTIONAL. Otherwise,
the client has a problem if it has the document data but the Printer only
Suggested re-wording of the sentence:
If a Printer object supports the Create-Job operation, it MUST also support
the Send-Document operation and it MAY support the Send-URI operation.
