NV Memory (Non-Volatile Memory) The printer's NV memory stores data even after the printer power is turned off. NV memory contains the following memory areas for the user: • NV graphics memory • User NV memory • Memory switches • Receipt Enhancement (R/E) • User-defined page • Maintenance counter As a guide when you program applications, NV memory should be rewritten 10 or fewer times a day. NV Graphics Memory Graphics, such as shop logos to be printed on receipts, can be stored. Even with a serial interface model whose communication speed is low, high speed graphic printing is possible. Use the TM-H6000IV Utility to register graphics. You can also print and confirm the registered graphics in the TM-H6000IV Utility or NV graphics memory print mode. • For detailed information about the TM-H6000IV Utility, see the TM-H6000IV Utility User's Manual. • For information about how to use the NV graphics memory print mode, see "NV Graphics Print Mode" on page 90. User NV Memory You can store and read text data for multiple purposes, such as for storing a note including customizing or maintenance information of the printer. Use ESC/POS commands to store and read the text data. For information about ESC/POS commands, see the ESC/POS Application Programming Guide. 22
