[Caution]

• Because frequent writing in the non-volatile memory can

 

destroy the memory, the writing command (FS g3) should be

 

used less than 10 times a day.

 

• It may happen that the printer becomes BUSY during the

 

process of writing data into the non-volatile memory while

 

this command is executed. When the printer becomes BUSY,

 

it will stop receiving data. Therefore, sending data from the

 

host (Including real time commands) is prohibited.
