Current printer status is transmitted..
•
Status sent out consists of 1 byte whose content is as in the table below.
•
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.
•
In DTR/DSR control, when the host is in unreceptible state(DSR signal being in
•
MARK state), it waits until receptible state is created.
•
In paper end (paper near end) status, this command may be unreceptible state due to BUSY state.
