US v n
[Name] Status confirmation by DTR signal
[Format] ASCII US v n
Hex 1F 76 n
Decimal 31 118 n
[Range] n = 0, 1, 48, 49
[Description] Sets the DTR signal in the host interface to the MARK or SPACE state.
[Notes] • When n = 1 or n = 49, the DTR signal goes to the MARK state.
If it is already in the MARK state, the DTR signal does not change.
• When n =0 or n = 48, the DTR signal goes to the SPACE state if the following
conditions are satisfied:
➀ The receive buffer is not in the buffer-full state.
➁ The self-test is not being executed.
If it is already SPACE when n = 0 is received, the DTR signal does not change.
• This command is effective only when the display alone is selected by
ESC = 2
.
Therefore, if the printer is already selected, this command (three bytes) is ignored and
is processed as normal data. (The data is transmitted to the printer.)
• If any data is received during status confirmation using the DTR signal, normal
interface timing control is executed immediately.

moved to the home position.
