INTRODUCTION
This chapter deals with the aspects
of
the PX-S involved with interfacing the
computer to other devices. Some
of
the devices are
an
integral part
of
the PX-S,
others can be purchased separately. Epson
is
continually developing further
products and so this manual cannot cover every device it is possible
to
use with
your PX-S. This manual does not mention specific products

these items vary from country
