Image data printing is ignored while printing is performed. 

If the image data exceeds one line, the excess data is not printed.

6-dot feed is performed regardless of the line feed pitch setting before
the stamp data is printed.

GS:

Set starting/ending
position of macro definition

<1Dh><3Ah>

Specifies the starting or ending position of the macro definition. 

If this command is received while defining the macro, it ends the
definition.

The macro range can be set up to 2048 bytes. 

Even if ESC @ is executed, the macro definition is not cleared. 

Normal printing operation is possible while defining the macro.

<1Dh><5Eh> ...

Executes the macro definition. 

r: Specifies the number of times to execute the macro. 
t:

Specifies the waiting time for executing the macro. 
Waiting time of t

×

100 msec is required for one execution:

Specifies the macro executing mode. 

m = 0 Continuous macro execution.

Executes “r” times continuously at the interval specified by
“t”. 

m = 1 Executes the macro by pressing the paper feed key.

After waiting the period specified by “t”, the ERROR LED
blinks and the printer waits for the receipt paper feed key
to be pressed. After the paper feed key is pressed, the
printer executes the macro once. The printer repeats this
operation “r” times.

If this command is received while defining the macro, the macro
definition is aborted. 

If the macro is not defined or if “r” is 0, nothing is executed. 

Paper cannot be fed with the receipt paper feed key while executing
the macro when “m” is 1.
