摘要： A method and apparatus for printing a print job includes determining which nozzles of a printhead are currently failing, estimating a number of additional printhead nozzles that will fail while printing the print job, calculating a maximum number of failing nozzles that may not be exceeded in order to maintain a specified quality level for the print job, and determining if the number of currently failing printhead nozzles added to the estimated number of additional printhead nozzles that will fail exceeds the calculated maximum number of failing nozzles. The method and apparatus also includes providing a notification in the event that the number of currently failing printhead nozzles added to the estimated number of additional printhead nozzles that will fail exceeds the calculated maximum number of failing nozzles.
