As a guide, NV memory rewriting should be 10 times or less a day when you program
applications.

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 graphics printing is possible.
Use the TM-T70II Utility to register graphics. You can also use the TM-T70II Utility or the NV graphics
information print mode to confirm the registered graphics.
