Macros
These commands are used to select and perform a user-defined sequence of printer operations.
Select or cancel macro definition
ASCII
GS :
Hexadecimal
1D 3A
Decimal
29 58
Starts or ends macro definition. Macro definition begins
when this command is received during normal operation
and ends when this command is received during macro
definition. The macro definition is cleared, during
definition of the macro when the execute macro (1D 5E)
command is received.
Normal printing occurs while the macro is defined. When
the power is turned on the macro is not defined.
The defined contents of the macro are not cleared by
the initialize printer (1B 40), thus, the initialize printer
(1B 40) command may be used as part of the macro
definition.
If the printer receives a second select or cancel macro
definition (1D 3A) command immediately after previously
receiving a select or cancel macro definition (1D 3A) the
printer remains in the macro undefined state.
Formulas
The contents of the macro can be defined up to 2048
bytes.
Exceptions
If the macro definition exceeds 2048 bytes, excess data is
not stored.
Execute macro
ASCII
GS ^ r t m
Hexadecimal
1D 5E r t m
Decimal
29 94 r t m
Value of r:
The number of times to execute the macro.
Value of t:
The waiting time for executing the macro.
Executes a macro. After waiting for a specified period the
printer waits for the paper feed button to be pressed. After
the button is pressed, the printer executes the macro once.
The printer repeats this operation the number of specified
times.
When the macro is executed by pressing the paper feed
button (m = 1), paper cannot be fed by using the paper
feed button.
Formulas
The waiting time is t x 100 ms for every macro execution.
m specifies macro executing mode when the LSB (least
significant bit) m = 0
The macro executes r times continuously at the interval
specified by t when the LSB (least significant bit) of
m = 1.
Exceptions
If this command is received while a macro is being
defined, the macro definition is aborted and the definition
is cleared.
If the macro is not defined or if r is 0, nothing is executed.
