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.

Returns whether this printer message from operator attribute is
equivalent to the passed in object. To be equivalent, all of the
following conditions must be true:

    

  1.  object is not null.

  3.  This printer message from operator attribute's underlying string and object's underlying string are equal. 
  4.  This printer message from operator attribute's locale and object's locale are equal. 


Params:
  • object –  Object to compare to.
Returns: True if object is equivalent to this printer message from operator attribute, false otherwise.
