The total capacity of the UV user memory is selectable as any one of these: [0, 64K, 128K,
or 192K] bytes with
GS ( E
. The default capacity is 1KB.
[Notes] • Frequent write command executions by this command may damage the NV memory.
Therefore, it is recommended to write to the 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.
