Now that the PIC is installed, you need to change the settings of three small switches, called DIP switches, in the back of the printer, Figure 1-2 shows where the DIP switches are.

Figure l-2. DIP switch location

The functions of these switches are explained in detail in Appendix D, but all that you need to do now is turn three of them on. All the others should be off. (The switches are down when they are off and up when they are on.) Before you change any of the DIP switch settings make sure that the power switch on the right side of the printer is turned off.

The DIP switches are in two groups, with eight in the first group and four in the second. Turn on switches 6, 7, and 8 in the first group. Now you are ready to test your printer.
