The switches are located at the back of the printer behind the plastic lid.
Set all DIP switch positions with the power OFF.
The DIP switches are read after the initialization process either by turning the power switch on or inputting the INITIAL signal of the parallel interface.
When shipped from the factory, all switches except for international character switches are turned OFF.

DIP Switch Bank 1

Note 1: Standard and IBM modes are selected only by using DIP switch 1-5. There is no control code to designate Standard or IBM mode.

Note 2: In Standard mode, DIP switch 1-6 determines whether a download character is valid or not. When a download character is valid, the communication buffer is reduced to 3K bytes from 6K bytes.

International Characters Selected by DIP Switches

Note 1: These character selections are valid for all character sets: Standard character set, IBM character set 1, and IBM character set 2.

Note 2: When DENMARK is selected by the DIP switches in IBM character set 2 mode, code (9B)Hex, or (155)Decimal will print a small slashed zero and code (9D)Hex, or (157)Decimal will print a large slashed zero.
