GS ( E pL pH fn [parameter]
[Name] To Customize NV memory area
[Description] Customize the NV user memory area. The table below explains the functions
available in this command. Executes commands related to the user setting
mode by specifying the function code fn.

1 GS ( E pL pH fn d1 d2
2 GS ( E pL pH fn d1 d2 d3

4 GS ( E pL pH fn a
[Notes] - pL, pH specifies (pL + pH x 256) as the number of bytes after pH (fn and
[parameter]).
- The user setting mode is a special mode to change the values in the NV user
memory with this command.
- In Function 2, the printer performs software reset. Therefore, the printer clears the
receive and print buffers, and resets all settings (user-defined characters, macros,
and the character style) to the mode in effect at power on.
- Frequent write commands by this command, may damage the NV memory.
Therefore, it is recommended to write to NV memory no more than 10 times a day.
- While processing this command, the printer is BUSY while writing data to the user
NV memory and stops receiving data. Therefore it is prohibited to transmit data
including the real-time commands during the execution of this command.
