Nv Memory; Nv Graphics Memory; User Nv Memory; Memory Switches (Customized Value) - Epson TM-T88 Series Technical Reference Manual

NV Memory

The printer is equipped with NV memory (Nonvolatile Memory) to store 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

• 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 transmission speed is low, high speed graphic printing is possible.
Use the TMFlogo logo registration utility to register graphics.
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.

Memory Switches (Customized Value)

You can configure the serial interface communication conditions and other various settings of the printer.
For more information, see
User-defined page
You can store character data in the user-defined page (character code table: page 255) so that you can also
print characters not resident in the printer.
Maintenance Counter
With this function, printer information, such as the number of lines printed, the number of autocuts, and
printer operation time after the printer starts working, is automatically stored in NV memory. You can read
the counter information with the Status API of the APD, OPOS ADK, or ESC/POS commands. You can use the
counter information for periodical checks or part replacement.
As a guide, NV memory rewriting should be 10 times or less a day when you program
applications.
