Introduction
Features
EPSON TWAIN Pro Network and EPSON Scan Server software
work together to directly contr ol all of the features of your EPSON
scanner in a networked environment. Through the use of these
software packages, you can share one or more scanners among
the users in a network and allow scanned images to be imported
into any T WAIN-compliant application.
EPSON TWAIN Pro Network software controls the functions of
your scanner just like EPSON TWAIN Pro software and can be
used in a networked environment. On the other hand, EPSON
TWAIN Pro software is designed to be used only in a stand-alone
configuration in which only one PC is connected to an EPSON
scanner.
EPSON Scan Server software is installed on a PC which is
connected to an EPSON scanner (hereafter, the PC is called the
scanner server PC), and makes the EPSON scanner shareable in
the network. The scanner can be accessed from all client PCs
which have EPSON TWAIN Pro Network software installed.
Introduction 1
The illustration below shows a sample network configuration in
which networked scanning is avail able. One o f the cli ents can be
connected to the scanner server PC and impor t a sca nned image
from the scanner. After disconnecting, another client can access
the scanner server PC.

If there are multiple EPSON scanners and scanner server PCs in

EPSON scanner can be connected to one scanner server PC.
