Normally, you do not need to change these settings. Change
them only when you have special requirements.
SLCT-IN-When you set SLCT-IN to OFF, the printer is
continuously selected and ignores device control codes DC1
and DC3. In almost all cases, leave SLCT-IN set to OFF. When
SLCT-IN is ON, the SLCT-IN signal goes HIGH at power-on
and the control codes DC1 and DC3 are valid.
Menu/submenu Available options
SLCT-IN OFF ON or OFF
AUTOFEED-When you set AUTOFEED to OFF, the printer
ignores the AUTOFEED signal on pin 14 and does not send an
automatic line feed (LF) command with each carriage return
(CR). When you set AUTOFEED to ON, the printer adds a line
feed to each carriage return it receives. If your text lines
overprint each other, set AUTOFEED to ON.
