[Name] Start/end macro definition
[Format] ASCII GS :
Hex 1D 3A
Decimal 29 58
[Description] Starts or ends macro definition.
[Details]
•
Macro definition starts when this command is received during normal operation.
Macro definition ends when this command is received during macro definition.
•
When
GS ^
is received during macro definition, the printer ends macro
definition and clears the definition.
•
Macro is not defined when the power is turned on.
•
The defined contents of the macro are not cleared by
ESC @
. Therefore,
ESC @
can be included in the contents of the macro definition.
