• ESC/POS Handshaking Protocol is required for this function.
[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.
