Epson 20 - Manual (Page 21)

Using the Parallel Interface
The Equity 386 parallel interface is Centronics®-compatible and uses a
DB-25S connector. Most Epson printers have parallel interfaces.
To connect a printer to the computer, you need an IBM-compatible
printer cable. If you are not sure which one you need, check with
your Epson dealer. Once you have the correct printer cable, follow
these steps to connect your printer to the parallel interface on the
computer:
1. Place the printer next to your computer.
2. Before you connect the printer, be sure the power switches on the
computer, monitor, and printer are off.
3. One end of the printer cable has a 25-pin, D-shell male
connector; this is the smaller connector. Connect this end to the
parallel port on the back panel of the computer, as shown below.
If the plug has retaining screws, tighten them by hand or with a
screwdriver, depending on the screw type.
