NV Memory (Non-Volatile Memory) The printer's NV memory stores data even after the printer power is turned off. NV memory contains the fol- lowing memory areas for the user: NV graphics memory User NV memory Customized values and memory switches User-defined page Maintenance counter As a guide when you program applications, NV memory should be rewritten 10 or fewer times a day. Graphics, such as shop logos to be printed on receipts, can be stored. Even if communication speed is low, high speed graphic printing is possible. Use the TM-P80 Utility to register graphics. You can also print and confirm the registered graphics in the TM- P80 Utility or NV graphics print mode.
For detailed information about the TM-P80 Utility, see the TM-P80 Utility User’s Manual. To use the NV graphics print mode, see "NV graphics information print mode" on page 58 . 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 detailed information about ESC/POS commands, see the ESC/POS Command Reference.
