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
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 pr
int mode.
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.
As a guide when you program applications, NV memory should be rewritten 10 or fewer
times a day.
