[Function] Editing user NV memory
[Outline] [The specification which is common to the model]
• Erases/stores/sends data of user NV memory area and sends the use amount/remaining capacity.
• Executes edit processing of user NV memory specified by function code (fn).

memory in a lump.
• pL, PH specifies the number of bytes of “m” and the following to (pL + pH x 256).
• c1, c2 specifies key code (ID code of record).
• Total capacity of user NV memory can be specified as any of [1K, 64K, 128K, 192K]bytes by GS ( E.
Default value is 192K byte.
[Caution] • Frequent use of this command may result in damage of NV memory. Use the Write command to
NV memory in consideration of [10 times max./day].
• Following the processing of this command, printer Busy may occur during writing data in NV
memory. While the printer is Busy, it stops receiving process. Therefore, data transmission
(including real-time command) from host is prohibited.
