• 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 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.
• 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.
