The present invention relates to a system and method for ensuring that a correct toner is used for printing a document. A printer receives data about a document requiring a specific toner type to print the document. The printer receives toner type identification from a toner cartridge inserted into the printer. The specific toner type required is compared with the available toner type in the cartridge. If the available toner type in the cartridge matches the specific toner type, the document is printed. If there is no match, the printer displays an error message and does not print the document.
