Setting Up the Printer
If you've been using your EPSON printer with your computer, the printer is
probably set up already. If so, turn off your system and disconnect the printer
from the computer. Then go to "Connecting the Cable" below to attach the
USB/Parallel Adapter cable to your system.
If you're setting up a new printer, see the documentation that came with your
printer for instructions on unpacking it, installing ink cartridges, and loading
paper. Then return to this booklet for instructions on connecting the cable
and installing your printer software.
Connecting the Cable
You can connect the USB/Parallel Adapter directly to a USB port on your
Macintosh or to a USB hub connected to a port on the Macintosh. If you
have any printing problems when the printer is connected via a USB hub, try
connecting the printer directly to a USB port on the computer instead.
