The DIP Switch FunctionsAuto line feed

When auto line feed is on (DIP switch 2-4 on), each carriage return code (CR) is automatically followed by a line feed code (LF).

Input buffer capacity

The input buffer stores data from your computer. If you want to free your computer for other tasks while the printer prints, change the setting of switch 2-5 to 8 KB (on). Before using user-defined characters, however, be sure to set the input buffer to 1 KB (off).

Printing direction

With unidirectional printing, the print head prints in one direction only. This allows for precise vertical alignment, making it ideal for printing graphics such as lines and boxes. With bidirectional printing, the print head prints in both directions. This is faster than unidirectional printing.

When DIP switch 2-6 is off, the printer prints unidirectionally; when it is on, the printer prints bidirectionally. Either setting can be overridden by a software command (ESC U).

To achieve precise vertical alignment without the slower printing speed caused by unidirectional printing, see your dealer for adjustment of your bidirectional print settings.

Tear-off mode

When DIP switch 2-2 is on, the short tear-off mode is on. This feature automatically advances continuous paper to the tear-off position, and then reverse-feeds the paper to the loading position. See Using Short Tear-off later in this chapter.

CAUTION: Do not use the short tear-off mode with labels.
