• The definition will start from NV bit image number 01H and n-number bit images will
be defined in ascending order. Therefore, the first data group [xL xH yL yH d1...dk]
becomes NV bit image number 01H, and the last data group [xL xH yL yH d1...dk]
becomes NV bit image number 0nH. These numbers of NV bit images coincide with
those specified with FS p.
• 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×256)×(yL＋yH×256)×8)＋Header: (4)] bytes
of non-volatile memory is used to store it.
• The maximum definition area of this printer is 2M bits (256K bytes). Multiple NV bit
images can be defined, but bit images of which total size (Bit image data + Header)
exceeds 2M bits (256K bytes) can not be defined.
• The printer state will change to BUSY just before the writing operation into the
non-volatile memory begins. Also,for a printer that have a dip switch [BUSY], the
printer state will change to BUSY just before the writing operation begins regardless of
the state of the dip switch.
• 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 starts 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.
• Just after the completion of the writing operation into the non-volatile memory, the
printer hardware will be reset. Therefore, download characters, download bit images,
and macro definition will be made undefined. The receiving buffer/printer buffer will be
cleared, and each setting will go back to its default value. Then the status of dip
switches will be checked once more.
• 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.
