Abstract
The present invention relates to a method and system used to ensure that a printer which is capable of printing security patterns loses its ability to print these patterns if the printer is disconnected from an approved system and, more particularly, to a method and system including a printer containing an encrypted key and password loaded into its memory, where the stored password must match a password present in a data stream sent from the host software application in order to print a requested print job.
