DIP Switches

Auto line feed

When auto line feed is on (DIP switch 2-4on), each carriage return code (CR) is automatically accompanied 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 to 8 Kbytes (DIP switch 2-5on). Before defining user- defined characters, however, be sure to set the switch to 1 Kbyte (off).

Print direction for graphics

The printer ordinarily prints text bidirectionally for speed and prints graphics characters unidirectionally for precise vertical alignment. You can, however, change text printing to unidirectional with the software command ESC U1. If DIP switch 2-6is on, you can change graphics character printing to bidirectional with ESC U0. If DIP switch 2-6is off, graphics character printing is unidirectional whether or not ESC U0 is used.

Page length

DIP switch 2-1 lets you select a page length of 11 inches (27.94 cm) or 12 inches (30.48 cm). If you are using paper that is 12 inches long, you can set this switch on. (Factory setting is off for 11 inch paper.)

Skip over perforation

DIP switch 2-3 controls the skip over perforation function. If this switch is on when you are using continuous paper, the printer leaves a one-inch margin between the last printed line on one page and the first printable line on the next page so that the printer skips over the perforation.

Most application programs take care of the top and bottom margins. Therefore, do not turn on skip over perforation unless your program does not provide these margins.
