Can you provide a concrete example of this?

Ideally any output tray/roll should be selectable via the "output-bin" Job Template attribute.  If there are constraints requiring the use of other Job Template attributes to "enable" a particular paper path, those should be enforced when accepting a print Job, either by returning the 'successful-ok-ignored-or-substituted-attributes' or 'client-error-conflicting-attributes' status codes with the corresponding attributes/values in the unsupported attributes group of the Create-Job/Print-Job/Print-URI response.

Similarly, the "job-constraints-supported", "job-resolvers-supported", and "job-triggers-supported" Printer attributes can be used to tell a Client what those constraints are and/or to trigger selection of the necessary companion attributes and values so that the Client UI can manage things prior to Job submission...
