DIP Switch 1-3 is ON
1) When the printer occure error, open the cover, when out of paper or feed paper, the printer only
stop working but not busy status.
2) When DIP Switch is ON and handshaking signal is effective, check the printer status by GS a and ASB
command. In this status, the default of GS a parameter n is 2. The printer transmit the printer status
automatically, it decided by online/offline status.
3) When use DLE EOT, should be confirm that the receive buffer area is not full enough.
•For example, when the printer is busy, the host can not transmit the data:
When receive buffer area full to make printer busy, if occur error, can not use DLE EOT
•If the printer is busy, the host can transmit the data:
When transmite bit image data, if receive buffer area full and process bit image date that transmit DLE
EOT at the same time that will be as bit image data.
When receive buffer area full, maybe lose the data if transmit.
For example: When use 4KB receive buffer area, after transmitting each lie data, check theprinter status by GS r
1. Transmit one line data to make the receive buffer is not full enough.

Reverse data mode
The status data transmission from the printer to the host is processed in the nibble or byte mode. NOTE: At
present, reverse data transmission by nibble.
□ Description
This mode allows data transmission from the asynchronous printer under the control by the host.
Data transmissions in the Nibble mode are made via the existing control lines in units of
four bits. In the byte mode, data transmissions are processed by making the eight-bit data lines
bidirectional.
The both modes fall to process concurrently with the compatibility mode, thereby causing half duplex
transmission.

NOTES: 1. A prefix “n” to signal names refer to low level active signals.
2. To the host provided with none of the signal lines listed above, both-way communication fails.
3. For interfacing, signal lines shall use twisted pair cables with the return sides connected to signal ground
level.
4. Interfacing conditions shall be all based on the TTL level to meet the following characteristics In addition,
both rise and fall time of each signal shall be 0.5|js or less.
5. Data transmission shall not ignore the signal n Ack or Busy. An attempt to transmit data with signal, nAck
or Busy, ignored can cause data lose. (Data transmission for the printer shall be made after verifying the
nAck signal or while the Busy signal is at the low level.)

Reception of status from the printer through the bidirectional parallel interface
In the bidirectional parallel interface specifications, the printer status transmission is available by
using the both-way communication facility in the Nibble/Byte Modes in accordance with the IEEE 1284.
In this case, different from in the RS-232 serial interface specifications, the real-time interruptions from the
printer to the host are disabled and thus precautions must be taken to the followings:
1) Allowable capacity of the printer internal buffer is 99 bytes (except ASB status), The status signals
exceeding this capacity will be discarded, To prevent possible loss of status, the host shall be ready for data
acception (Reverse Mode).

2) When ASB is used, the host is preferably in the wait state for data acception (ReverseIdle Mode).When this
state is not available, the host shall enter the Reverse Mode to always monitor the presence of data.
3) When ASB is used, preference shall be given to the ASB status for transmission over the other status
signals. Once one ASB conditions changed, all ready to send ASB conditions from last time that need to send
