Class PrinterMessageFromOperator is a printing attribute class, a
text attribute, that provides a message from an operator, system
administrator, or "intelligent" process to indicate to the end user
information about or status of the printer, such as why it is unavailable or
when it is expected to be available.
A Print Service's attribute set includes zero instances or one instance of a
PrinterMessageFromOperator attribute, not more than one instance. A
new PrinterMessageFromOperator attribute replaces an existing
PrinterMessageFromOperator attribute, if any. In other words,
PrinterMessageFromOperator is not intended to be a history log. If it
wishes, the client can detect changes to a Print Service's
PrinterMessageFromOperator attribute and maintain the client's own
history log of the PrinterMessageFromOperator attribute values.
IPP Compatibility: The string value gives the IPP name value. The
locale gives the IPP natural language. The category name returned by
getName() gives the IPP attribute name.
