Transmits data from user NV memory.

m is always set to 0.

a1, a2, a3, and a4 specify the data stored starting address to (a1 + (a2 × 256) × (a3 ×
65536) + (a4 × 16777216)).

nL, nH select the number of stored data bytes (nL + (nH × 256)).

The printer transmits all data collectively without confirming whether the host is ready to
receive data. To receive all data result correctly, (the capacity of the transmitted data +
2) bytes or more space is required in the receive buffer.

During data transmission, the printer ignores real-time commands. Also, the printer
does not transmit ASB even when the ABS is enabled. Therefore, the user cannot
confirm changes in the printer status during these periods.

User NV memory means the memory area which is used for storing character font data
in non-volatile memory.

If the values of the argument (m), the stored starting address (a1, a2, a3, a4) and the
number of the stored data (nL, nH) are out of the specified range, or if the stored staring
address (a1, a2, a3, a4) + the number of the stored data (nL, nH)
≥
1024, this command
is ignored and data following are processed as normal data.

After the data is ready to be transmitted, the printer executes the following process:
transmits [ Data + NUL].

The contents of [ Data + NUL] are as follows:
Header: Hexadecimal = 5FH / Decimal = 95 (1 byte)
Data: Data stored in user NV memory ((nL + (nH x 256)) bytes)
NUL: Hexadecimal = 00H / Decimal = 0 (1 byte)

The printer transmits all data consecutively without confirming whether the host
computer is ready to receive data. The data transmission must be consecutive, except
for the XOFF code.

Data which is stored in the user NV memory can be written by FS g 1 .
