Connecting a Parallel Printer
You can use the PRINTER port to connect a parallel device, such as
a Centronics ® -compatible printer. Before connecting a printer,
check the manual that came with it to see if you need to change
any of its settings.
You can also connect some third-party external diskette drives to
this port. Check with the Epson Connection for product
compatibility requirements. If you do connect an external diskette
drive to this port, be sure to run the Setup program to identify the
drive.
Follow these steps to connect a parallel device:
1. Place the printer or other device in a convenient location near
your computer, so that the power and data cables will not
interfere with the paper or paper trays.
2. Make sure both the computer and printer are turned off.
3. Connect the printer cable to the PRINTER port.
