Setting the DIP Switches

The DIP switch functions

This section describes the different features you can control with the printer’s DIP switches.

Slashed zero

When DIP switch l-2is on, the printer prints slashed zeros(0). When the DIP switch is off, the printer prints open zeros (0). This feature is useful for clearly distinguishing between uppercase 0 and zero when printing documents such as program lists.

Printer mode

When DIP switch l-4is on, the printer operates in IBM emulation mode. When the DIP switch is off, the printer operates in Epson ESC/P mode. The functions of DIP switches 1-3,1-6,1-7,1-8,and 2-1 in IBM emulation mode differ from their functions in Epson ESC/P mode. The tables on the previous page describe the special functions of these DIP switches in IBM emulation mode.

Default character set

When DIP switch 2-l is on, the user-defined character set is the default. User-defined characters are maintained in the printer’s memory even when the power is turned off, so you can select the user-defined character set simply by turning on this DIP switch. However, when the switch is on, you cannot define new user- defined characters. The setting of this DIP switch takes effect only if DIP switch l-4is set for Epson ESC/P mode. See Chapter 4 for more information on user-defined characters.

Draft printing speed

When DIP switch 2-2is off, high-speed draft mode is selected. When the switch is on, normal draft mode is selected. This switch only affects the printer if DIP switch 1-5is set for draft mode (turned off) or if draft mode is selected through your software. In high-speed draft mode, the DFX-8000 can print up to 1066 characters per second at 10 cpi (characters per inch). In normal
