NOTE   =VIEW AND PRINT WITH A MONOSPACED FONT!!!!!!!!
  
  The serial interface board at the back of the printer contains two DIP switches, one 8-pin switch (SW 1-1 to SW 1-8), and one 4-pin switch (SW2-1 to SW2-4), which permit you to select various conditions.

Although these switches are set at the factory, you may change them to suit your application. The function and factory-set condition of each switch are shown below.
