The D-Link DP-G321 Print Server is an 802.11g wireless Multi-Port Print Server that
allows you to connect your USB printer or parallel printer directly to your network.
Now you can locate printer services virtually anywhere in your home or office. The
DP-G321 manages the flow of print files from workstations or file servers to
connected printers, delivering print jobs to printers much faster than a file server on
a PC.
The DP-G321 includes easy-to-use software to install on most Windows-based
networks. Protocol support for TCP/IP, NetBEUI, and AppleTalk are provided to
ensure seamless connection to major networking operating systems.
The DP-G321 has a built in Web-based management feature that allows users to
easily configure and manage print queues through TCP/IP.
The DP-G321 provides a 10/100Mbps auto-sensing Ethernet port, allowing flexible
attachment to either 10BaseT or 100BaseTX networks. With two USB 2.0 ports
and one standard parallel port, the DP-G321 is an ideal wireless high-speed Print
Server for a home or office that has multiple printers.
The DP-G321 improves network printing services in the following ways:
The DP-G321 delegates print jobs to the network printer. This provides
workload relief to your file servers and allows the file servers’ full capacity
to be used for file access or other direct services to network users. On
peer-to-peer networks, workstations can print directly to the Print Server
without increasing the load of another workstation or server.
The DP-G321’s USB 2.0 ports can transmit data to high-speed laser
printers much faster than a PC’s parallel printer port. With a separate
parallel port, you will still have the option to use a standard parallel printer
with the DP-G321.
Introduction
Because the DP-G321 is very portable and inexpensive compared to a
PC-based print server, and the Print Server connects to your file servers
through the network, printers can be deployed to locations of maximum
convenience to users.

External Features
Port Connectors
The DP-G321’s two USB ports and parallel port are located on its rear panel. The
printer port can be configured using the PS Admin program or the print server’s
Telnet interface. (See the PS Admin User’s Guide, available on the CD that came
with the DP-G321, for information about configuring the print server’s ports.) The
Print Server also supports web configuration permitting users to configure settings
through the web browser. The default IP Address is as follows:
Default IP Address – 192.168.0.10
Subnet Mask – 255.255.255.0
The DP-G321 offers extraordinary flexibility, operating with all major network
operating systems and protocols:
TCP/IP
UNIX lpr/lpd
Windows NT/2000, Windows 95/98SE/Me, Windows XP
NetWare 5.x NDPS LPR Remote Printing
NetBEUI
Windows 2000/XP, Windows 95/98SE/Me, Microsoft LAN
Manager, IBM LAN Server
AppleTalk
MacOS EtherTalk
Windows-based setup and administration software, PS Admin, is supplied with
the Print Server, making configuration and management quick and easy. The
Print Server also supports configuration and management via the Telnet protocol
for networks without Windows-compatible systems.
Note:
The PC’s IPAddress must be in the same subnet as the Print Server’s IPAddress for the
two devices to communicate. (For example, if your Print Server’s IP Address is
192.168.0.10, with a subnet mask of 255.255.255.0, then your computer’s IP Address
should be 192.168.0.x, where x is a value between 1-254, excluding 10.)

D-Link wireless products are based on industry standards to provide easy-to-use
and compatible high-speed wireless connectivity within your home, business or
public access wireless networks. D-Link wireless products will allow you access to
the data you want, when and where you want it. You will be able to enjoy the
freedom that wireless networking brings.
A wireless LAN (WLAN) is a cellular computer network that transmits and receives
data with radio signals instead of wires. WLANs are used increasingly in both home
and office environments, and public areas such as airports, coffee shops, and
universities. Innovative ways to utilize WLAN technology are helping people to work
and communicate more efficiently. Increased mobility and the absence of cabling
and other fixed infrastructure have proven to be beneficial for many users.
Wireless users can use the same applications they use on a wired network.
Wireless adapter cards used on laptop and desktop systems support the same
protocols as Ethernet adapter cards.
Wireless Basics
People use wireless LAN technology for many different purposes:
Mobility - Productivity increases when people have access to data in any location
within the operating range of the WLAN. Management decisions based on real-
time information can significantly improve worker efficiency.
Low Implementation Costs –WLANs are easy to set up, manage, change, and
relocate. Networks that frequently change can benefit from WLANs ease of
implementation. WLANs can operate in locations where installation of wiring may
be impractical.
Installation and Network Expansion - Installing a WLAN system can be fast and
easy and can eliminate the need to pull cable through walls and ceilings. Wireless
technology allows the network to go where wires cannot go - even outside the
home or office.
Scalability – WLANs can be configured in a variety of topologies to meet the
needs of specific applications and installations. Configurations are easily changed
and range from peer-to-peer networks suitable for a small number of users to
larger infrastructure networks to accommodate hundreds or thousands of users,
depending on the number of wireless devices deployed.
Inexpensive Solution - Wireless network devices are as competitively priced as
conventional Ethernet network devices.

Standards-Based Technology
Based on the IEEE 802.11g standard, the DP-G321 is interoperable with existing
compatible 2.4GHz wireless technology with data transfer speeds of up to 54Mbps
when used with other D-Link AirPlus G devices.
Wireless Basics (cont.)
Installation Considerations
The D-Link AirPlus GDP-G321 lets you print through your network, using a
wireless connection, from virtually anywhere within its operating range. Keep in
mind, however, that the number, thickness and location of walls, ceilings, or other
objects that the wireless signals must pass through, may limit the range. Typical
ranges vary depending on the types of materials and background RF (radio
frequency) noise in your home or business. The key to maximizing wireless range
is to follow these basic guidelines:
Keep the number of walls and ceilings between the DP-G321 and other
network devices to a minimum - each wall or ceiling can reduce your D-Link
wireless product’s range from 3-90 feet (1-30 meters). Position your devices
so that the number of walls or ceilings is minimized.
2.
Be aware of the direct line between network devices. A wall that is 1.5 feet thick
(.5 meters), at a 45-degree angle appears to be almost 3 feet (1 meter) thick. At
a 2-degree angle it looks over 42 feet (14 meters). Position devices so that the
signal will travel straight through a wall or ceiling (instead of at an angle) for
better reception.
3.
Keep your product away (at least 3-6 feet or 1-2 meters) from electrical
devices or appliances that generate extreme RF noise.
5.
Building materials can impede the wireless signal - a solid metal door or
aluminum studs may have a negative effect on range. Try to position wireless
devices and computers with wireless adapters so that the signal passes
through drywall or open doorways and not other materials.
4.
Keep the antenna of the DP-G321 in an upright position.

Setting up the DP-G321
Installing the Print Server
WARNING: Configuration problems may result if the Print Server is powered up without
first establishing its network connection. Follow this procedure to avoid complications at
the configuration stage.
Confirm proper operation of your printer before connecting the DP-G321.
1.
When you have confirmed proper operation of your USB or parallel printer, turn
your printer power OFF.
2.
Confirm that your network is operating normally.3.
Connect the DP-G321 to your network, using a straight-through CAT5 cable.
4.
While the printer is powered OFF, use the USB or parallel printer cable to con-
nect the DP-G321 to your printer.
5.
Switch ON your USB or parallel printer.
6.
Plug the DC power adapter into the DC 5V power socket on the rear panel of
the Print Server.
7.
Plug the power adapter into a power outlet. This will supply power to the
DP-G321, as it has no external power switch. The green Power LED on the
Print Server’s front panel should illuminate steadily, and the Print Server’s
Self-Test will proceed.
8.

11
Immediately after power-up, three of the green LEDs should illuminate steadily for
several seconds. Then the USB LED should flash three times. Irregularity of the
LED during this LED test may mean there is a problem with the LED itself.
The actual component tests immediately follow the LED tests. A normal (no fault)
result is signaled by a flashing of the USB LED, followed by a darkened LED.
If the Self-Test routine detects any component error, then following the LED tests
the Self-Test will halt and the LEDs will continuously signal the error according to
the following table.
When the DP-G321 is powered ON, it also automatically performs a Self-Test on
each of its major components. The final result of the Self-Test is signaled by the
state of the USB LED indicator following the Self-Test. Preliminary to the actual
component tests, the LED indicators are tested to confirm their steady and flashing
operation.
