Software switch 2-2, it is recommended to place at Off. In this way, the printer
performs an automatic paper cut each time when the top cover is closed (e.g.
after paper roll loaded) with the printer in operating condition. However, if it
placing in ON, it will not automatically cut paper after top cover closed.
For switch position 2-4,
when it set to “OFF”, the paper will feed before
cutting when software does not define this point and there will be a further
paper feeding after cutting to prevent last 2 lines cutted. Before setting this
switch to “ON”, please make sure that your software will take care of enough
paper feed for printed lines cut prevention issue.
For switch position 2-5, if the switch is set to “ON”, the busy signal set to host
only when input buffer is full. When it is set to “OFF”, busy signal is sent to
host whenever the input buffer is full or an off line status occurs. Therefore,
signals including the paper near end detect will generate busy signal to the host.
Moreover, the printer will keep on beeping at Paper End (completely no paper)
till paper is replaced when S2-5 is “ON”. When S2-5 is “OFF”, the printer will
keep on beeping every 3 seconds at Paper Near End (still long paper in replace)
till paper is replaced.
For switch position 2-6 and when it is set to ON, the printer responds to a
carriage return command (CR code or 0Dh) with also a line feed (LF code or
0Ah) action. Then if the text editor always expresses the change to a new line
with both the CR and LF codes, there will be an extra line advance than
expected. However it works for some old editors that express the change to a
new line with only either one of the LF code or the CR code.
Switch position 2-7 defines the parity check regulation in serial interface.
In PP-8800, it is selectable between even and none.
For switch position 2- 8 can choice 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”.
