[4]Other errors

When trouble is detected in the printer mechanism, the ALARM lamp goes on, the buzzer is sounded, the FAULT signal is output, and the DTR signal becomes BUSY. After the cause of the trouble has been corrected, the ALARM lamp can be turned off by pressing the LINE switch or by making RESET = "0". When the printer is put ONLINE, data receiving restarts.

(4)Data Receiving Control

When the BUSY signal is LOW, your printer receives data from the host side, but when this signal is HIGH, it cannot receive data.

(5) Buffering

Data transfer to the input buffer is controlled by the DTR and TD signals. Please refer to 9.3 b) for the DTR signal and 9.3 f) for the TD signal.
