Switch position 4 defines the handshaking method in serial interface. When it is set to ON, the printer transmits an “XOFF” for busy and sends an “XON” for not busy. When it is set to OFF, the printer signifies the busy status over hardware signals that can be detected by the host as “DSR” or “CTS”. When parallel interface is used, both switch positions 3 and 4 should be set to OFF.
For switch position 5, if the switch is set to ON, the busy signal is sent to host only when input buffer is full. When it is set to OFF, busy signal is sent to host whenever an off line status occurs. Therefore, signals including the paper near end detect will generate busy signal to the host. Consequently, the printing may be stopped even when there is still a long way to go before the paper roll is actually exhausted. Taking the paper out beep into consideration, the printer will keep on beeping at Paper End (completely no paper) till paper is replaced when
For switch position 6, when it is set to OFF, there will be a 20 mm paper feed before cutting when software does not define this point and there will be further 10 mm paper after cutting to prevent paper jam. Before setting this switch to ON, please make sure that your software will take care of enough paper feed for the paper jam prevention issue.
For switch position 8, when it is set to ON in the field, the printer maybe subject to unpredictable damages and must be strictly prevented.
The factory default for each position is listed below:
5 - 3
