EXECUTING COMMAND

	•	The pulse ON time is [t ⋅ 100] ms, and the OFF time is [t ⋅ 100] ms.
[Notes]	■	The printer executes this command upon receiving this command.
	■	This comand cannot be executed when the unrecoverable error occurs.

■ With a serial interface model, this command is executed even when the printer is offline, the receive buffer is full, or there is an error status.

■ With a parallel interface model, the printer cannot receive data when it is busy; therefore this command cannot be used under the following conditions.

• When DIP Switch 1-6 is On: receive buffer-full.

• When DIP Switch 1-6 is Off: receive buffer-full, offline, error status.

■ This command is executed any time the data sequence <10>H<14>H<n><m> <0> is received, even if it appears as part of another command.
