>> If the "job-presets-supported" and/or "job-triggers-supported" attributes are settable using Set-Printer-Attributes, they must be listed in the "printer-settable-attributes-supported" attribute. Any limits to the sizes of the attributes are handled at request time through the "client-error-request-entity-too-large" status code - see section 4.1.3 of RFC 3380.
