Macro Function Commands
Function Start/End Macro Definition
ASCII [GS] :
Hexadecimal 1DH 3AH
Decimal
<29> <58>
Description The [GS] : command starts or ends macro definition. Macro definition starts
when the command is received during normal operation and ends when it is
received during the macro definition. The macro definition can contain up to
2048 bytes. If the definition exceeds 2048 bytes, the excess data will not be
stored.

Description The GS ^ r t m command executes a macro definition. The r specifies the
number of times to execute the macro. When Bit 1 of m is set, r is ignored, and
the macro is executed infinitely. t specifies the waiting time for executing the
macro; it is t
×
100 msec for every macro execution. m specifies macro
executing mode. When the LSB of m = 0, the macro executes r times
continuously with the interval specified by t. When the LSB of m = 1, the printer
remains idle and waits for the FEED Button to be pressed (after waiting for the
period specified by t). After the button is pressed, the printer executes the macro
once. The printer repeats the operation r times. When Bit 5 of m is set, the
current macro definition is saved into the printer’s nonvolatile flash memory as a
start-up macro without executing it. The macro definition is executed upon
power-up using the parameters specified by the GS ^ r t m command. If the
printer is powered-up into self-test mode, the macro definition will not be
executed. A saved macro definition can be deleted with the GS _ command.
