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.
If the printer receives GS : again immediately after previously receiving
