(24) Transmitting the printer status (ESC v)
Code : [1B]h + [76]h
Current printer status is transmitted..
l Status sent out consists of 1 byte whose content is as in the table below.
l In DTR/DSR control, after receptible state of the host (DSR signal being in SPACE state)
is confirmed, only 1 byte is transmitted. In XON/XOFF control, DSR signal state not being
confirmed, only 1 byte is transmitted.
l In DTR/DSR control, when the host is in unreceptible state(DSR signal being in
MARK state), it waits until receptible state is created.
l In paper end (paper near end) status, this command may be unreceptible state due to BUSY state.
Remarks. This command is valid only for serial interface model.

(25) Transmitting the status of Peripheral Equipment (ESC u n)
Code : [1B]h + [75]h + n
* {n = 0}
Current status of connector pin No.3 is transmitted.
l "n" means the followings.
n (Hex) Condition
0 Drawer Kick Connector No. 3
l Status transmitted consists of 1 byte whose content is as in the table below.
l Any equipment has not been connected to this connector, Bit 0 of n is always "1".
l In DTR/DSR control, after receptible state of the host (DSR signal being in SPACE state) is
confirmed, only 1 byte is transmitted. Further, in XON/ XOFF control, DSR signal state
not being confirmed, only 1 byte is transmitted.
l In DTR/DSR control, when the host is unreceptible state (DSR signal being in MARK state),
it keeps waiting until receptible state is created.
