DIP switch 1

Use this switch to change the horizontal print position according to the size of your paper. If you are using letter size paper or envelopes, leave this switch set to OFF; the left margin will be 0.25 inch (6.4 mm) and the maximum print width will be 10.5 inches. If you are using A4 size paper, set this switch ON; the left margin will be 0.13 inch (3.4 mm) and the maximum print width will be 11.4 inches.

DIP switch 2

If you are using a software application that assumes 66 lines will fit on each page, set this switch to ON. The printer will reduce the line spacing by a factor of 14/15, which is from 63 lines per page to 66 lines per page if line spacing is set to 6 lines per inch (lpi).

DIP switch 3

Use this switch to turn on reduction mode. In this mode, the printer reduces characters and graphics to two-thirds of their normal size. When the printer is in envelope mode, reduction mode is disabled.

If you are using letter size paper, set this switch Off; this sets the page length to 11 inches. If you are using A4 size paper, set this switch ON; this sets the page length to 12 inches.

When this switch is OFF, the printer uses the Epson Italics character set, which includes italic characters. When this which is ON, the printer uses the Epson Graphics character set, which is the same as the MS-DOS code page 437 (this character set includes symbols, lines, corners, and European characters). See Appendix C for information on the character sets.
