Product Introduction
Figure 1: The HP Print Server PSA 4250
The HP Print Server Appliance 4250 is a state-of-the-art device for managing and monitoring printing over a network. It is a network device that has been designed to provide a quick and easy way to add print capacity without affecting the general purpose server. It has several distinct advantages over conventional network printing configurations which can result in improved performance in both printing and file access. These advantages are
discussed below.
Microsoft NT domain security, also known as Microsoft NT Authentication and Authority, is a feature that allows
administrators to easily authorize or restrict print administration and services to specific groups or users by using their existing user name and password of the NT 4.0 domain. An NT domain is a logical grouping of network servers and other computers that share a common security and user account for each user. Users log on to the domain, not to individual servers in the domain.
Installing printers on each client computer is required in order for clients to be able to print using the PSA. With the Microsoft Point and Print technology, printers are added to the PSA and associated with a factory-installed driver or a driver already associated with a printer. Clients can be easily set up with access to that printer and its driver without having to install the driver again.
In a typical network, general purpose servers manage both the printing tasks and the file/application serving. The PSA handles the spooling and network traffic associated with printing, reducing the workload on the general purpose server.
When printing takes place at remote offices or other locations distant from the servers, the speed of printing can be degraded. A PSA installed in a remote office can dramatically increase printing performance by eliminating the need for print requests to travel from the remote office to the central site and back to a remote office printer.
An additional benefit is that if general purpose file/application servers go down, remote office users can still print many jobs directly, using the PSA.
Operation and Management
Once the PSA is configured, virtually no management tasks are required. However, system administrators can monitor print activity, manage the printers, or alter the configuration of the PSA from anywhere on the network using the PSA's web-based graphical user interface and a supported browser, or by using Web Jetadmin.
Web Jetadmin plug-ins have been designed to configure and manage multiple PSAs. The Web Jetadmin plug-ins for PSA firmware version 2.4.x. are dependent on Web Jetadmin (version 7.2). The Web Jetadmin plug-ins provide LAN administrators and IT managers a single tool to manage their printing environment. The plug-ins provide the following management capabilities for the PSA:
●Automated migration of printers from Microsoft Windows servers
●Automated migration of existing printer connections on Microsoft Windows clients
●Auto-discovery of PSAs
●Batch configuration of most settings
●Remote print path creation
●Remote management of printer drivers
●Central device status reporting
●Scheduled batch firmware upgrades
●Scheduled backup/restore of configuration settings
Product Description
The PSA contains a large disk drive for spooling print jobs from clients. Print jobs are stored on the disk drive. The number of print jobs is only limited by the disk space available on the PSA.
The PSA provides web-accessible printer management and configuration and spools print jobs from the following clients:
●Microsoft Windows 95
●Microsoft Windows 98
●Microsoft Windows 2000
●Microsoft Windows NT
●Microsoft Windows ME
●Microsoft Windows XP
●UNIX
Following are some main features of the PSA:
●Off-loads spooling from a UNIX or Windows NT server
●Easy installation
●Easy management
Centralized management using Web Jetadmin

●Windows NT Domain integration
●Line Printer Daemon (LPD) support for UNIX clients
Compatibility with HP Print Servers
The PSA will work with any HP print server with firmware version x.03 and above.
Compatibility with Other (Non-HP) Print Servers
Any print server that supports LPD should work with the PSA. The proper LPD remote queue name for the print server might have to be known. Many print servers will work without specifying a remote queue name (use the default HP PRINT SERVER setting); however, some require a special string in order to work. The LPD remote queue name can be obtained from the print server vendor.
Product Updates
When new firmware or other device-specific support information is available for the PSA, the PSA can be notified automatically. On the TCP/IP and DNS page, a field Check for print server PSA firmware updates during each web login can be checked to enable this feature. If this is checked and new firmware or support information is available, the picture of the PSA image on the Overview page in the web interface will change.
This feature is enabled by default and can be disabled by unchecking this box. Each time an image is retrieved, it is logged like any other visit to HP's website. In addition, each request includes the serial number of the requesting unit. HP uses this to provide support information relative to the specific unit. No personally identifiable information such as user name, email address, or physical address is gathered as part of this process. HP does monitor web logs in order to understand our customers and improve our products.

Links to related documents:
Troubleshooting the Appliance
Installing printers on each client computer is required in order for clients to be able to print using the PSA.
Note: Hewlett-Packard recommends verifying installation with one client computer before configuring more clients. This will confirm operation. It is easier to troubleshoot settings on one client computer than on many.
Installing Printers on Microsoft Clients (the Microsoft Point and Print feature)
Use one of the following procedures to install printers on each client computer (this feature is only supported on an x86 PC running Microsoft Windows 9x, ME, NT, 2K, or XP). Before you begin, check the following:
●The PSA is installed on the network and properly configured.
●Each client workstation is connected to the network.
●The printers are set up and turned on.
For Windows 9x, ME, NT, and 2K:
1.On the client workstation, click Tools in Microsoft's Explorer and select Find… Computer. Type the name or IP address of the PSA. Or, find the PSA in the Network Neighborhood.
2.Open the Printers folder.
3.Right-click on the printer to install.
4.Select Install from the drop-down menu.
5.For Windows NT, 2000, and XP clients, driver installation is complete. For Windows 95, 98, and ME clients, a wizard will ask several things (for example, Do you want to print from DOS, and so forth.).
Or:
1.On the client workstation, click Start-->Settings-->Printers.
2.Double-click the Add Printer icon.
3.Select the Network print server radio button.
4.Select the PSA and printer from the list box. Or, type the Universal Naming Convention (UNC) path (for example: "\\spooler1\printer1"). See Microsoft documentation for more information about UNC. Click OK.
5.Answer subsequent questions to complete the driver installation.
For Windows XP:
1.On the client workstation, click Start and then choose My Computer. Under Other Places, click My Network Places. Now click Search on the toolbar and type the name or IP address of the PSA.
2.Double-click the PSA that was found. This will expand into a list of printers available on the PSA.
3.Right-click on the printer and click Connect to install. The printer should now be in the printers and faxes folder.
Or:
1.On the client workstation, click Start and then choose Printers and Faxes.
2.Under Printer Tasks select Add a printer.Double-click the Add Printer icon.
3.Select the Network print server radio button.
4.Select the Connect to this printer radio button and type the Universal Naming Convention (UNC) path (for example: "\\spooler1\printer1"). See Microsoft documentation for more information about UNC. Click Next.
5.Answer subsequent questions to complete the driver installation.
Bypassing Point and Print
Installing printers on each client computer is required in order for clients to be able to print using the PSA. With the Microsoft Point and Print technology, when a printer is added to a client, an associated driver is automatically installed on the client also. This helps make printer installation easy. However, the driver associated with a given printer can only be managed at an administrator level, so changes to that driver such as enabling duplex or changing the driver itself will be reflected on all Windows NT, 2K, and XP clients using that printer; only one driver can be associated with a given printer.
In order to bypass this functionality, clients can install a local printer that uses a local port to print through the PSA.
Note: This requires the client to install a driver locally. Because the installed printer is viewed by the computer as a local printer, it will not receive job status feedback from the PSA. For example, if the printer on the PSA has been paused, the client printer will not reflect this and it may look like a job was printed when it was not.
To install a local printer with local driver that prints through the PSA, follow the following steps.
For Windows 2000 and XP Clients:
1.Start the Add Printer wizard (in Windows 2000 or XP).
2.Click Next.
3.On the Local or Network Printer screen, select Local printer and then click Next.
Note: On this screen, make sure Automatically detect and install any Plug and Play printer is not selected.
4.On the Select the Printer Port screen, select Create a new port and then select Local Port as the Type. Click Next.
5.On the Port Name screen, type the UNC name for the printer in the following format and click OK:
\\<psa_name>\<printer_name> (where "psa_name" is the name of the PSA and "printer_name" is the name of the printer)
6.On the screen showing printer manufacturers and printers, select a printer driver and then click Next.
7.On the Name Your Printer screen, specify a printer name and then click Next.
8.On the Printer Sharing screen, select Do not share this printer and then click Next.
9.On the Print Test Page screen, click Next.
10.Click Finish.
For Windows NT Clients:
Note: Before you begin, make sure you have Microsoft's Service Pack 6a (or greater) installed on the client(s).
1.Start the Add Printer wizard (in Windows NT).
2.Select My Computer and click Next.
3.On the screen showing available ports, click on the Add Port button.
4.On the Printer Ports screen, select Local Port and then click New Port.
5.On the Port Name screen, type the UNC name for the printer in the following format and click OK:
\\<psa_name>\<printer_name> (where "psa_name" is the name of the PSA and "printer_name" is the name of the printer)
6.Click OK.
7.On the Printer Ports screen, click Close.
8.On the screen showing available ports, select your newly created port and click Next.
9.On the screen showing printer manufacturers and printers, select a printer driver and then click Next.
10.On the screen asking for a printer name, enter your printer name and click Next.
11.On the screen referring to printer sharing, select Not Shared and click Next.
12.Click Finish.
Configuring Printing for UNIX Clients
The following topics are discussed in the section:
●configuring print queues for BSD-like systems
●configuring print queues using SAM (HP-UX systems)
●printing a test file
A print queue must be set up for each printer or printer personality (text, PCL, or PostScript) used.
If printing text documents from UNIX clients to an HP Jetdirect print server, a special queue must be configured on the PSA. First add the printer through the Print Share page in the web interface. On the Identify Printer page, for
connectivity select Other and then specify the Remote Queue Name. For the remote queue name on the target printer, TEXT must be specified (or TEXT2, TEXT3 for multi-port Jetdirect print servers). This must be done even though the target printer is an HP Jetdirect device. Use the normal print queue when printing jobs that have been formatted with a printer-specific page description language such as PDL (like PostScript) or PCL.
Configuring Print Queues for BSD-like Systems
If the printer supports automatic language switching, the application may select the printer language using commands embedded in the print data.
Make sure users know the printer names for the printers, since they will have to enter those names on the
command line for printing.
Following is an example of configuring print queues for BSD-like systems (for example, Linux):
1.Edit the /etc/printcap file to include the following entries:
printer_name:\ :lp=:\
:rm=print_appliance_name:\
:rp=remote_printername_argument:\ (this should be the same as the printer name on the appliance)
:lf=/var/spool/lpd/error_log_filename:\ :sd=/var/spool/lpd/printername:\
:sh:
where printer_name is the name of the printer on the local computer. , print_appliance_name identifies the printer on the network, and remote_printername_argument is the print queue designation on the appliance.
For more information on printcap, see the printcap man page in the UNIX documentation.
2.Create the spooling directory by making the following entries. As the root user, enter:
cd /var/spool/lpd mkdir printername chown root printername chgrp lp printername chmod 755 printername
where printername is the name of the printer on the local computer.
Configuring Print Queues Using SAM (HP-UX Systems)
On HP-UX systems, the SAM utility can be used to configure remote print queues for printing.
Before the SAM program is executed, select an IP address for the appliance and set up an entry in the /etc/hosts file on the system running HP-UX. (This is not required if DNS is configured.)
1.Start the SAM utility as a super user.
2.Select Printers/Plotters from the Peripheral Devices menu.
3.Select LP Spooler.
4.Select Printers/Plotters from the Printers/Plotters menu.
5.Select Action from the top menu and then select Add Remote Printer or Plotter.
6.Complete the Add Remote Printer/Plotter screen.
The Printer Name field should be the local printer name.
Be sure to check the box Remote Printer is on a BSD System.
7.Click OK.
8.Select Exit from the List menu.
9.Exit SAM.
Printing a Test File
To verify that the printer and PSA connections are correct, print a test file.
1.At the UNIX prompt type:
lp -dprintername file_name or on a BSD-like system:
lpr -Pprintername file_name
where printername is the name of the printer as added to the appliance, and file_name is the file to be printed.
2.To get print queue status, type the following at the prompt: lpstat printername
or on a BSD-like system: lpq -Pprintername
where printername is the designated printer. Example: lpq -Pappliance1
Front Panel

Troubleshooting the PSA
The following activities can be performed from the front panel:
Start Up or Shut Down the PSA
Configure the IP Address for the PSA
Configure the Link Speed and Duplex Mode for the PSA
Set or Change the Front Panel Password
The front panel on the HP Print Server Appliance 4250 has the following components:
LEDs
There are four indicator lights (LEDs) on the front of the PSA. Understanding how the lights function is important for proper operation of the PSA. This page describes normal and problem LED status displays.
LED |
LED Name |
Description |
Power LED |
ON when power is supplied to the PSA and it is turned on. |
Network Activity LED LIT when there is a connection between the PSA and other network devices. BLINKS when there is network activity between the PSA and other network devices.
Disk Activity LED ON when there is disk activity on the PSA.
Alert LED |
OFF during normal operations (ON during bootup and shutdown). |
Power Button - Starting Up and Shutting Down the PSA
Press the Power button to power up the PSA. The bootup process begins. When the device is powered on, the Power LED is lit. To turn off the PSA, press the Power button and wait for about 20 seconds for the PSA to power down. The PSA performs an orderly shutdown.
If print jobs are printing when the PSA is powered down, the print jobs will not be completed. Jobs waiting to be printed will resume printing when the PSA is fully booted. If the PSA loses power unexpectedly and is not powered down, spooled print jobs that had not yet begun printing or print jobs that were in the middle of printing will resume printing when power is restored and the PSA is powered up again. If, however, the integrity of the PSA or print jobs are compromised, print jobs that were not spooled would have to be resent.

Messages on the Front Panel
When the PSA is powered up, it executes a series of self tests. It then displays a series of messages, including "Booting...
Configuring... Validating... Extracting... Formatting..." etc.
When the startup process is complete, the PSA displays a repeating series of normal operating messages.
The first line of the display shows the PSA name which can be entered from the web interface during configuration (on the
Microsoft Network Settings page). If the name is not typed in the web interface, the default name, based on the device's MAC address, is displayed.
The second line of the display shows date, time, IP address, and firmware version in a repeating sequence.
Starting Front Panel Operation
Configure the IP Address for the PSA
Configure the Link Speed and Duplex Mode for the PSA
Set or Change the Front Panel Password
There are three front panel operations: IP configuration, link speed and duplex mode configuration, and password configuration
Use the web interface to further configure the PSA. Refer back to the Getting Started procedures, or refer directly to information about using the web interface to further configure the device.
Configuring the IP Address Using the Front Panel
These procedures explain how to configure an Internet Protocol (IP) address on the PSA using the front panel. (The TCP/ IP and DNS page in the web interface can also be used to do the same.) Configuring the IP address allows the PSA to route print tasks properly.
If the network does not use Dynamic Host Configuration Protocol (DHCP), use the front panel of the PSA to manually enter the IP address, subnet mask, and default gateway.

After a moment, the PSA will resume displaying normal operating messages if the IP address is valid.
Configuring the Link Speed and Duplex Mode Using the Front Panel
These procedures explain how to configure the link speed (100 Mbps or 10 Mbps) and the duplex mode (full or half) for the PSA using the front panel. This can be done manually or the settings can be automatically detected (which is the default). The link speed is the speed at which the PSA communicates over the network. The speed is expressed in megabits per second and is either 10 or 100. The duplex mode defines whether data can be sent at the same time it is received:
●Full duplex: data can flow both directions at the same time
●Half duplex: data can only flow one way at a time and any attempt to do both at the same time creates a collision.
The current setting is displayed on the System Summary page (under Maintenance in the web interface).

Setting or Changing the Front Panel Password
There are two types of passwords that can be set for the PSA: a front panel password (one per PSA) and an administrator password (can be multiple accounts, but there must be at least one), which enables access to the web interface to manage the PSA. The front panel password is discussed in this section.
There is no front panel password until it is set. This password limits access to front panel functions. A password will prevent unauthorized configuration changes. After the front panel password is set, it must be entered before future configuration tasks can be performed at the front panel display.
To set or change the front panel password, press 
once. The following messages are displayed:
Press 
Press 
.
Type a new password and press

Or, after a moment, it will display normal operating messages.
