[Description]
Transmits the number of bytes of remaining memory (unused area) in the downloaded graphics area.
•
This function does not require ESC/POS Handshaking Protocol.
[Notes]
■
This function is used to send the following data groups, beginning with the Header and ending with NUL.
(*1) The unused capacity is the total byte count for the unused area.
■
The decimal value for the unused capacity is converted to text data and sent starting from the high order
end.
Example:
If the available capacity is 120 bytes, the “120” (expressed hexadecimally as 31H, 32H, and 30H, decimally
as 49, 50, and 48) is converted to 3-byte data.
■
The control information for download graphics data is included in the capacity in use.
■
Do not use this function in conjunction with download bit images (
GS
✻
) and download characters
(
ESC &

See previous [Notes for transmission process] for process sending data group.
