❑Print direction. Specifies how the print head moves across the page. The options are Uni-D, Bi-D, and Auto (default). When Uni-D is on, the print head prints in only one direction to provide the most precise alignment for graphics and text. In Bi-D printing, the print head prints in both directions. Bi-D is faster but the vertical alignment may not be as precise as Uni-D. When Auto is selected, the printer switches automatically between bidirectional (for text data) and unidirectional (for graphics data).

❑Font and Pitch. Select the built-in printer font and character pitch used as the default. Normally you use your software to select the font and pitch. The default Font and Pitch is Courier 10 cpi (characters per inch).

❑Interface mode. Selects the active interface. The default setting, Auto, allows the printer to automatically switch as needed between the parallel and serial interfaces. However, if you experience communication problems, you might want to set the interface mode to either Parallel or Serial.

❑Auto interface wait time. Sets the time period for the printer to wait for data from the current interface (and accept no data from the other interface) when you’re using the Auto interface mode. You can select a 10-second (default) or 30-second wait time.

❑Software. Specifies the printer control language to use: EPSON ESC/P 2 (default) or IBM X24E. If your software allows you to select EPSON ESC/P 2, choose it for the most advanced fonts and graphics.

❑Auto CR. Specifies that the printer perform a carriage return and line feed operation if the print positions exceed the right margin of the paper. (Used in IBM X24E mode only.)
