[Description] The printer sends the host the number of data bytes currently used in the
NV memory area.
- ESC/POS Handshaking Protocol is not required for this function.
[Notes] - With this function, the printer sends the "Header to NUL"
data shown below:
- The decimal value expressing the capacity being used is converted to
ASCII character data and sent from the most significant digit.
Example :
When 120 bytes is used, the number 120 is expressed with
three bytes of data (Hexadecimal: 31H, 32H, and 30H / decimal numbers
49, 50, and 48).
When no memory area is used, the number 0 is expressed with
1 byte of data. (Hexadecimal: 30H / decimal number 48).
- See previous [Notes for transmission process] for process sending
data group.

[Notes] - When the specified record exists, the printer sends the "Header to NUL"
data shown below:
(*1) When the quantity of stored data exceeds 80 bytes, the printer
performs partial processing, using the following rules:
- If there is unsent data, the identification status of the third byte is
41H or 65 decimal.
- If there is no unsent data, the identification status of the third byte is
40H or 64 decimal.
(*2) The printer performs batch processing when the data to be stored in the
specified record is 80 bytes or less. At this time, the identification status
of the third byte is 40H or 64 decimal.
(*3) The key code and terminator are not included in the data.
(*1) The quantity of stored data bytes, plus the key code and terminator, equal
the capacity being used.
- If the host specifies a nonexistent record, the printer sends the
"Header to NUL" data shown below:
- See [Notes for transmission process] for description of transmission
process.
- See [Notes for ESC/POS Handshaking Protocol] for description of
ESC/POS Handshaking Protocol.
