• The definition data of one NV bit image consists of [xL xH yL yH d1… dk] . Therefore, when only one NV bit
image is defined, n = 1; the data group [xL xH yL yH d1… dk] is manipulated once, and ( [Data: (xL + xH
x256) x( yL + yH x256 ) x8 ] + [Header: 4] ) bytes of non-volatile memory is used to store it
• The maximum definition area of printer depends on model. Multiple NV bit images can be defined, but bit
images of which total size (Bit image data + Header) exceeds capacity of definition area can not be defined.
• The printer state will change to BUSY just before the writing operation into the non-volatile memory begins.
Also, the printer state will change to BUSY just before the writing operation begins regardless of the state of
the MSW even at a printer that have a MSW 1-3 [Busy condition]
• While this command is being executed, it is not possible to send ASB status or to detect the printer status even
when the ASB function is selected.
• If this command is sent while a macro is still being defined, the definition process will be stopped and the
execution of this command will start.
• NV bit images that are defined already are not initialized by using ESC @ command, or by resetting the printer
or turning the power off.
• The command only executes definition of NV bit image, but not start printing. The printing of NV bit image will
be executed by FS p.
• Because frequent writing in the non-volatile memory can destroy the memory, the writing command 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 in the execution of this command. When the printer becomes BUSY, it will stop receiving data.
Therefore, sending data from the host (including real time command) is prohibited.
