Note: You can plug some printers into the unswitched AC outlet on the back panel, if the printer’s power consumption does not exceed 1.5 amps.

Serial interface

If you have a printer (or another peripheral such as a modem) with a serial interface, connect it to the port marked SERIAL on the back panel of the main unit. If your cable has a male D-connector at both ends, you need an adapter to connect it to the computer. To connect a serial device, follow the same steps above for connecting a parallel device.

To use a printer connected to the serial port, you need to use the MS-DOS SETMODE program (or the MODE command) to indicate the RS-232C serial port is in use and to direct printer output to the serial instead of the parallel port. See your MS-DOS manual for instructions.

The Equity II character set

The Equity II uses a special character set that assigns graphics and international characters to some ASCII codes. In most cases, if you try to print these characters on a standard printer, you get italic characters in- stead. Some Epson printers support the IBM character set (the character set the Equity II uses) as a standard feature, and you can adapt others. Also, some application programs can print the special graphics characters on a standard printer when you use a special printer driver program. Ask your Epson dealer for more information.
