[Notes]
•
Frequent write command executions by an NV memory write command may damage
the NV memory. Therefore, it is recommended to limit writing the commands into the
NV memory to 10 times or less a day.
•
If the power is turned off while this command is being executed, the printer may go
into an abnormal condition. Be careful not to turn the power off while this command
is being executed.
•
While processing this command, the printer may become BUSY while writing data to
the NV memory and stops receiving data. Therefore, be sure not to transmit data
from the host PC while the printer is BUSY.
•
After transmitting <Function 1, 4, 6, and 12>, do not transmit the subsequent data until
the status is received.
