■
With a serial interface, when DTR/DSR control is selected by DIP switch
(handshaking), the printer transmits [Header~NUL] to the host after
confirming that the host is ready to receive data.
■
With a serial interface, when XON/XOFF control is selected by DIP switch (handshaking), the
printer transmits [Header~NUL] to the host without confirming that the host is ready to
receive data.
■
With a parallel interface, a [Header ~ NUL] is stored at first in the transmission buffer with
the other transmission data (except for ASB status). When the host becomes Reverse Mode,
the data is transmitted in order from the beginning. Data which exceeds the transmission
buffer size (99 bytes) is ignored. When using the command, the host should be Reverse
Mode immediately and execute receive processing of status.
■
When using this command, space for the receive buffer of the host should be more than
((
n
L
+
n
H
x 256) + 3) bytes.
■
When transmitting data, ASB status and real-time commands cannot be used.
