[Notes] ▪ pL, pH specifies (pL + pH x 256) the number of bytes after pH (fn and

▪ 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 when writing data to
the user NV memory and stops receiving data. Therefore, it is prohibited to
transmit data including real-time commands during the execution of this
command.
