[Outline] The memory switch is stored in the nonvolatile EEPROM memory. To change this setting, send
a command from the host side. After setting with the command, turn on the power again, or
reset with the following reset command, to enable setting. (If reset with the command, self-
printing will be implemented.)
Reset command: <ESC> <CAN> <LF> <NUL>
[Caution] The EEROM has a data-writing life. Do not execute this command every time. Note that if the
EEROM’s life is running out due to frequent use of this command, printer operation cannot be
guaranteed.
The memory switch segment numbers other than 3 to 5 do not have relevant setting items, but
they actually exist. Therefore, use of other numbers besides 3 to 5 will be valid as a command
and change the data in the EEROM. If this is the case, operation will not be guaranteed.
Exercise full care when using this command.
