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.
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.
