Macro Commands
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.
