API.
Inherits From:
MCollectible
Inherited By:
TLowlevelStatus
Purpose:
The abstract printing status class.
Instantiation:
Allocate on the heap or the stack.
Deriving Classes:
Deriving classes must override ClearStatus. They must override NotifyChangeInStatus for something meaningful to happen because the default implementation does nothing.
Concurrency:
Not multithread safe.
Resource Use:
No special requirements.

- Called to copy an object.
Parameters:
Return Value:
None.
Exceptions:
Throws no exceptions, passes all exceptions through.
Concurrency:

Other Considerations:
None.
virtual ~ TPrintingStatus ()
Interface Category:
API.
Purpose:
