Auto line feed

When DIP switch 3-3 is on, the printer adds a line feed (LF) command to every carriage return (CR) code sent by the application program software. When the switch is off, line feeds occur only when the software sends line feed commands to the printer. Since most computers and application programs automatically add line feeds to carriage returns, you should use this feature only if your text is printing all on one line.

Buzzer (beep)

The printer beeps when an error occurs. See Chapter 8, “Troubleshooting,” for more information. If you do not want the printer to beep, turn DIP switch 3-4 on.

Auto CR (carriage return)

This function is available only in IBM 2381 Plus emulation mode. When DIP switch 3-5 is on, each line feed (LF) code or ESC J code is accompanied by a carriage return (CR) code so the printer moves the next printing position to the left margin. When the switch is off, you must send a CR code after the line feed code to move the printing position to the left margin.

IBM character table

This function is available only in IBM 2381 Plus emulation mode. When DIP switch 3-6 is on to select table 1, hex codes 80H to 9FH of the character tables are used for the control codes. When DIP switch 3-6 is off to select table 2, hex codes 80H to 9FH are used for characters. See Appendix B for character samples.
