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.

Abstract: A set of new printing functions are implemented as defining commands to make it possible to add graphic effects to a printout of a POS printer. These functions are based on a method of designating usually cyclically re-occurring byte strings, usually text in receipts, to act as triggers to launch the graphics function. These functions include optionally eliminating some text, adding graphic surrounds about designated lines, changing the color of designated lines, and inserting logos between or merging logos with text. Such usage need not make any changes to existing store lane checkout applications. Configuring new custom commands in POS printers permits defining byte string triggers occurring in receipt text that are used to trigger adding graphics to the receipt output.

Abstract: The present invention uses the capabilities provided by configuring linked command sequences to provide for logo headers, logo trailers, watermarks, and margin message logos as configuration options. Additionally, the ability to map existing text attributes to new sets of attributes that may include color is also provided.
