(1) SW2-1: When the switch is ON, printer is permanently in the "selected" mode
and no external command can "deselect" it.
In the OFF position, it theoretically can be selected and deselected by external
software codes.
This refers to pin 36 on the connector. Some computers control this pin; if they
do control the pin, SW should be OFF.
(2) SW2-2: If ON, buzzer will sound, and if OFF, buzzer will not sound at all.
(3) SW2-3: This pin is used to set the automatic skip-over perforation function.
1) When this pin is set to the ON position, the I-inch automatic skip-over
perforation will be performed.
By this function, the paper automatically advances to the first line of the
next page when the remaining page length is 1 inch.
2) When this pin is set to the OFF position, the I-inch automatic skip-over
perforation will not be performed.
(4) SW2-4: Forces automatic LF with each CR. When OFF, LF must be provided
via software as needed. This pin is used to fix AUTO FEED XT signal
internally. The signal line is wired ORed with pin No. 14 of the interface
connector. To control pin No. 14, leave this DIP switch in the OFF position.
