process.
- See [Notes for ESC/POS Handshaking Protocol] for description of
ESC/POS Handshaking Protocol.

[Format] ASCII GS (
Hex 1D 28
Decimal 29 40
[Range] (pL + pH x 256) = 6 ( pL = 6, pH = 0)
m = 0
fn = 6, 54
b = 0
d1 = 67
d2 = 76
d3 = 82
[Description] The printer deletes all records stored in the NV user memory.
- All area is changed to unused area.
[Notes] This command is effective only at the beginning of the line.
This command cannot include macros; therefore, do not use this command
when defining macros.

[Name] Enable/disable real-time command
[Format] ASCII GS ( D
Hex 1D 28 44
Decimal 29 40 68
[Range] (pL + pH x 256) = 3, 5 ( pL = 3, 5, pH = 0)
m = 20
a = 1
b = 0, 1, 48, 49
[Default] a = 1/ b = 1 (DLE DC4 fn m t ( n = 1): enable)
[Description] Specifies enable or disable of a real-time command.
- pL, pH sets the number of parameters after pH (m and [a1 b1]...[ak bk])
to (pL + pH x 256) bytes.
- a specifies the type of real-time command.
- b specifies enable/disable of real-time command processing.
a b
Disable DLE DC4 n m t ( n = 1): output a specified pulse in real-time
0, 48
(It does not process)
1
Enable DLE DC4 n m t ( n = 1): output a specified pulse in real-time
1, 49
(It does process)
DLE DC4 n m t (n=1): output a specified pulse in real-time.
[Notes] - The printer processes each real-time command that is enabled upon
receiving it.
- A real-time command specified as disabled is not processed.
- The setting of this command is effective until ESC @ is executed,
the printer is reset, or the power is turned off.
- If you transmit a command for a bit image or defined data that contains the
sequence DLE DC4, be sure to disable real-time command processing
before transmitting the bit image or defined data command.
Then the printer will process the sequence DLE DC4 as image data.
