DIP Switches

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 U 1.

If you want to increase printing speed, you can change graphics character printing to bidirectional by turning DIP switch 1-5on. If DIP switch 1-5 is off, graphics character printing is unidirectional whether or not you use ESC U o.

High-speed draft

By setting DIP switch 1-6on, you can print at up to 330 cps (characters per second) if you select the 12 cpi draft font. The printer reduces the number of dots in each draft character to increase the printing speed.

If you select emphasized printing or condensed printing during high-speed draft mode, printing speed temporarily switches to normal draft speed until the enhancement is turned off. Also, if a line contains superscript, subscript, dot-graphics, or downloaded characters, printing speed switches to normal draft speed for that line only.

Input buffer capacity

The input buffer stores data sent from your computer. If you want to free your computer for other tasks while the printer prints, turn DIP switch 1-7off to select the 8 KB input buffer.
