[Description] Transmits the number of bytes of remaining memory (unused area) in the NV user memory.
• ESC/POS Handshaking Protocol is not required for this function.
[Notes]
■ With this function, the printer sends the “Header to NUL” data shown below:
(*1)
The available capacity indicates the number of bytes not being used.
■ The decimal value for the available capacity is converted to ASCII character data and sent from the most
significant digit.
Example: When 120 bytes is available (not being used), the number 120 is expressed with
3 bytes of data (Hexadecimal: 31H, 32H, and 30H / decimal numbers = 49, 50, and 48).
■ See previous [Notes for transmission process] for process sending data group.
