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 • R/E (Receipt Enhancement) • User-defined page • Maintenance counter As a guide, NV memory rewriting should be used 10 times or less a day when you program applications. Graphics, such as shop logos to be printed on receipts, can be registered. Even with a serial interface model whose communication speed is low, high speed graphic printing is possible. Use the TM-T20 Utility to register graphics.
You can also use the TM-T20 Utility or the NV graphics information print mode to print and confirm the registered graphics. • For information about the TM-T20 Utility, see the TM-T20 Utility User’s Manual. • For information about how to use the NV graphics information print mode, see "NV Graphics Information Print Mode" on page 71 . 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 Quick Reference or the ESC/POS Application Programming Guide.
With the memory switches, which are software switches for the printer, you can configure various settings of the printer. For information about the memory switch, see "Setting the Memory Switches/Receipt Enhancement" on page 43 . 20 NV Graphics Memory User NV Memory Memory Switches
