[Description] W rites data to NV user memory.
• m is always set to 0.
• a1, a2, a3, and a4 specify the data stored starting address to
(a1+(a2×256)×(a3×65536)+(a4×16777216)).
• nL, nH select the number of stored data bytes (nL+(nH×256)).
• d specifies the stored data.
[Details] • NV user memory means the memory area which is used for stor ing character font data in
non-volatile memory.
• This com mand is available only when processed at the beginning of a line in standard mode.
• This com mand is ignored in page mode.
• W hen this command is received during macro definition, the printer ends macro definition and
begins executing this command.
• If the values of the argum ent (m), the stored starting address (a1, a2, a3, a4), and the
number of the stored data (nL, nH) are out of the specified range, or if the stored starting
address (a1, a2, a3, a4) + the number of the stored data (nL, nH) ≥ 1024, this command is
ignored and data following are processed as normal data.
• If the value of the stored data d is out of range, the execution of this command is ended, and
data following are processed as normal data.
In this case, the data which are stored in the NV memory still remain.
• W riting data to the NV memory overwrites previous data. Therefore, previous data is deleted.
• If an error occur s during writing data to the NV memory, “Memory or Gate array R/W error”
appears.
• Data which are stored in the NV user m emory can be read by FS g 2.
• Once data is stored in the NV user m emory, it is not erased by executing ESC @, FS q, reset,
or power off.
[Notes] • Frequent write command execution by FS g 1 may damage the NV memory. Therefore, it is
recommended to write the NV memory 10 times or less a day.
• W hile processing this command, the printer is BUSY when writing the data to the NV user
memory and stops receiving data. T herefore it is prohibitted to transmit data including the
real-time commands during the execution of this command.
