• 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 a 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.
• The customized values can be reviewed with Function 4, 6, 12, or 50, even though the printer
does not enter the user setting mode.
[Notes] • 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 NV user
memory and stops receiving data. Therefore it is prohibited to transmit data including the
real-time commands during the execution of this command.
