[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.
