DATA
(a) When the IJ printer is off-line
¡
The NAK code is transmitted in response to an ENQ code reception from the
outside.
(b) When the IJ printer is on-line
¡
Transmission data is received from the external device. When it contains no
error, the ACK code is transmitted. In this instance, the "ready for reception"
state is maintained.
¡
If the data transmitted from the external device is in error, the NAK code is
transmitted after receipt of the ETX code.
In this instance, retransmit the data beginning with the ENQ code.
(c) Data retransmission
¡
Transmission data is received from the external device, and subsequent
transmission data is accepted. In this case, the received data is accepted
even if the DC2 (retransmission) code is not attached.
(d) Printing during reception
¡
While data is being received from the external device, the previously printed
contents are printed.
(e) Transmission data received from the external device
¡
Error-free transmission data is stored in the IJ printer. The same contents
are printed until different transmission data is transmitted to the IJ printer.
(f) When a data transmission is aborted (the transmission of up to the
ETX code is not completed)
1 Transmit the DC2 (retransmission) code to the IJ printer.
2 Press the Comm On/Off key to enter the off-line mode, and then switch back to
the on-line mode.
