NV Memory (Non-Volatile Memory)

The printer has NV memory which includes the user NV memory and NV graphics memory that
users can use.
NV memory can be rewritten about 100,000 times. As a guide, NV memory rewriting should
be 10 times or less a day when you program applications.
CAUTION

User NV Memory

Characters can be stored in the user NV memory.
Use ESC/POS commands to write or read them.
For detailed information about ESC/POS commands, see the ESC/POS Application
Programing Guide.

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 Flash Logo Setup utility for NVRAM to register graphics.
