Description of the HP Print Server Appliance
The PSA is a network device used to manage and monitor printing (Figure 1). It has been designed
to provide a quick and easy way to add print capacity without affecting the general-purpose server. It
off-loads print spooling and printing services from general purpose file servers.

Step 1: Connect the Cables
Connecting the cables is a 3-step process:
1. Rackmount the PSA (optional). A rackmount kit is shipped with the PSA for mounting it into an
industry-standard rack or server cabinet. Follow the instructions in the kit for mounting.
2. Plug in the network cable. The network connection for the PSA (located at the rear of the PSA)
will automatically sense your network speed and sync up to that speed. This is non-configurable.
The PSA runs at 10mb (10 BaseT) or 100 mb (100 BaseT). The LEDs on the back of the PSA
(near the RJ-45 connector) indicate the current speed. The PSA also detects whether your
network connection is capable of running at full- or half-duplex.
3. Plug in the power cable to the back of the PSA and turn it on by pressing the Power button on the
front panel.
Step 2: Configure the IP Settings
The PSA must have an IP address before it can complete its boot up cycle and route print jobs
properly. If your network uses Dynamic Host Configuration Protocol (DHCP), the PSA obtains an IP
address, subnet mask, and default gateway automatically. Go to Step 3.
If a DHCP server does not respond, the PSA displays a message asking you to manually configure
the IP address. Manual IP configuration of the PSA is accomplished through the front panel buttons
and the LCD display. Press the checkmark on the front of the PSA to start entering the IP address,
subnet mask, and default gateway.
After the PSA is configured with the IP address, subnet mask, and default gateway, additional
configuration information can be entered through the web interface.
Step 3: Access the PSA’s Web Interface
You must use Microsoft ® Internet Explorer (version 5.5 or greater) or higher), or Netscape Navigator
(version 6 or greater) to access the web interface for the PSA.
Point your browser to the PSA by typing the PSA’s IP address. You will be prompted to type a user
name and password. The default user name (admin) and default password (admin) can be used.
The PSA’s Overview page (Figure 2) is displayed with the PSA’s configuration information, including
the default PSA name, IP settings, and firmware version.

Step 4: Configure TCPIP Network Settings
To continue configuration the PSA, select TCP/IP and DNS under Networking. (The information in
the gray box in Figure 3 was provided by the DHCP server or by you in Step 2 above.)
Figure 3 – TCP/IP and DNS Settings Page
On the TCP/IP and DNS Settings page, type information about a Domain Name Server (DNS). DNS
allows network resources such as PCs and printers to be specified by a friendly name instead of an
IP address. It is used by the PSA to locate itself or other network entities.
On this page, configure the:
Domain Name Server (DNS) address: To ensure that the PSA functions correctly in large
networks with many subnets, a DNS server should be used. Type the IP address of that server in
this field.

DNS Domain Name: The fully-qualified Domain Name should be entered in this field. The
default DNS host name of the PSA is taken from the PSA system name.
In addition to configuring the DNS setting on the PSA, DNS entries for the PSA must be made in the
forward and reverse lookup tables on the DNS server.
If you do not have DNS settings configured correctly on the PSA or on the DNS server, you may
experience the following:
Slow performance when connecting to the PSA via Network Neighborhood
Slow response when opening a printer’s properties page
When new firmware or other PSA-specific support information is available, your PSA can
be notified automatically. On the TCP/IP and DNS Settings page, check the field Check
for print server appliance firmware updates during each web login. When new
firmware or support information is available, the picture of the PSA on the Overview
page in the web interface will change.
Step 5: Configure Microsoft® Network Settings
Microsoft networking configuration settings must be configured on the PSA (Figure 4). These settings
define the parameters for how the PSA appears and behaves on the network.
Figure 4 – Microsoft Network Settings Page
The following fields are on Microsoft Network Settings page:
Print Appliance Name – By default, the PSA name starts with HPX followed by the last 6 digits
of the hardware MAC address. This name:
PSA 4250 Install and Configure

shows up on the PSA front panel during boot-up and in normal operating mode.
is the DNS Host name for the PSA.
is the default NetBIOS name for the PSA that will show up in your Network Neighborhood.
Dashes (-) cannot be used as the first character of the PSA name.
Primary and Secondary WINS Server Address – Windows Internet Name Service (WINS)
enables network resources such as PCs and printers to be specified by their friendly or NetBIOS
names instead of their IP addresses. WINS is also used for NetBIOS name registration on all
subnets and to enable browsing across subnets.
It is important to have the WINS server address configured properly because it is the first protocol
used by the PSA to attempt name resolution for most network names. If configured incorrectly
the PSA can experience slow performance.
To resolve a name on the network, the PSA will first use WINS. If this fails a NetBIOS
broadcast will be attempted. If that fails, a DNS lookup will occur. In a large network with
many subnets containing both Windows ® and UNIX machines, DNS and WINS will be
used together.
To verify that the WINS and network browsing is functioning properly, try pinging the NetBIOS
name of the PSA from the command prompt. If you receive an error, verify that the WINS IP
information entered is correct and verify the address with the network administrator.
Windows Domain or Workgroup – Type the workgroup name or domain name that you want
the PSA to be installed in. By default, the PSA installs itself in the workgroup “workgroup”.
The nbtstat command can be used to assist in diagnosing status of the PSA in the network as
well as to verify WINS functionality. To use this command, type nbtstat –a <psaname> at a
command prompt.
NT Domain Authentication - Access to a printer share is granted based on the domain user’s
individual and group rights and permissions. Security is configured on an individual printer basis.
In this mode, a machine account is created on the primary Domain Controller (PDC); the PSA
uses authentication and authorization to determine if an individual is a member of the domain,
and has sufficient rights to access a printer on the PSA. If you choose not to add the PSA to a
domain, do not check this box. In this case, all users have print access to all of the print shares
on the PSA.
NT Domain Controller - You can set the PSA to automatically find the PDC in your network, or
manually specify these controllers by either IP address or NetBIOS name. If you set the PSA to
automatically discover the PDC, you must be using WINS on your network and have configured
the PSA to use WINS.
Create an account for this device in the NT domain - In order to use the Domain mode
security, a machine account will have to be created on the PDC. This can be done through the
NT native tools (server manager), or through the PSA’s web interface by the following routine.
1. Check the box that says Create an account for this device in the NT domain at the bottom
of this page.
2. Type an administrator name and password for the Domain. This is not the same as the
administrator’s name for the PSA.
If the PSA has problems creating a system account, try the following steps:
PSA 4250 Install and Configure
© Copyright Hewlett-Packard Company 2003
Verify that the Domain administrator name and password are correct.
Try to create a system account directly on the PDC through server manager.
Step 6: Set-up Administrator Accounts
The PSA manages security through:
Local accounts (for user mode installation): Administrator names are added directly to the
local account group on the PSA. The names should match NT account names and passwords.
All administrators will have the same access rights to the PSA.
NT Domain accounts (for Domain Mode installation): Add administrator accounts on the
Administrators page (Figure 5). If using Microsoft’s Internet Explorer, administrators with Domain
Admin accounts on the PSA will be automatically authenticated on the PSA using NTLM and will
not be prompted for a password.
Add a domain account

Step 7 – Configure Print Shares and Drivers
Print shares and drivers are added to the PSA and managed on the Print Share List page (select
Print Shares under Print Services, Figure 6). If you click Add, the Add Printer Wizard is started.
This is a three-screen wizard that walks you through adding a print share.

Start the Add Printer
Driver Wizard
Figure 6 – Print Share List Page
On the last screen in the wizard, you must install a driver for the print share. The driver can be a preloaded driver (already on the PSA), or you can add a new driver by clicking Add Driver (Figure 7).
New Driver button
Figure 7 – Adding a New Driver through the Wizard
To install print shares and drivers, your PC must be running NT, 2K, or XP operating system AND you
must have Power User rights or better on the PC you are using.
Before drivers can be initialized, Java Scripting must be enabled (in Internet Explorer, under: Internet
Options-->Security (tab)-->Custom Level (button)-->Scripting-->Scripting of Java Applets
(subheading). It is recommended that you first select either the 2K or NT version of the driver and
then add the additional supported OS drivers if you need them. Repeat this process for each print
share to be installed onto the PSA.

Once the print share is configured with its driver on the PSA, clients can install the print share.
Enabling and Disabling Drivers. On the Driver Management page (under Print Services), you
can enable and disable drivers. A driver that has been installed and initialized properly will be
enabled and available to work in the driver download model. That is, the driver will automatically be
pushed to the client upon printer installation.
A disabled driver is displayed with a tilde (~) in front of it in the driver list on the Driver Management
page. Drivers can be disabled in the following situations.
Manually disabled drivers. If you want to remove the point and print functionality from a printer,
you can disable the driver yourself. If a driver is disabled clients, will be prompted to install it
manually. (The printer driver name that is installed locally on the client must match the name of
the driver on the PSA that is disabled.)
Automatically disabled drivers. If a printer driver goes through the installation procedure but
fails the initialization step, the printer will still be created on the PSA but the driver for that printer
will be disabled automatically. A disabled driver will not be automatically installed onto a client
during printer installation. To try initializing the driver again, repeat the steps to add the driver
through the Driver Management page. If it still fails to initialize, select a different driver for that
After you have configured your PSA, you should back-up the settings and register your PSA.
Saving the configuration parameters makes it easy to restore those parameters if the PSA must be
replaced or if its configuration values are accidentally changed or lost. Use the Backup Settings page
(under Backup/Restore) to save the following configuration parameters:
administrator account user names and passwords
network settings
print share information
printer drivers
To register your PSA, go to: http://www.hp.com/go/printappliance_registration.
The PS was designed to quickly and easily integrate into your existing network. By using the existing
protocols and services like WINS, DNS and NetBIOS Broadcasts, the PSA will seamlessly become
part of your network at a fraction of the cost of more conventional print spooling devices.
Ensuring a proper configuration on the PSA and in the network infrastructure eliminates most of the
installation and configuration roadblocks and ensures proper functionality of the PSA.
