Handling Error Conditions in a Message Override
You use the message cleanup functions when you encounter an error during the processing of certain printing messages that change the state of your driver. When you call a cleanup function, QuickDraw GX sends a corresponding cleanup message to all of the handlers in the message chain, allowing them to revert to their previous state.
