1 Overview
What is an embedded Web server?
A Web server provides an environment in which Web programs can run, in much the same way that an operating system, such as Microsoft® Windows®, provides an environment in which programs can run on your computer. A Web browser, such as Microsoft Internet Explorer, Apple Safari, or Mozilla Firefox, can show output from a Web server.
An embedded Web server resides on a hardware product (such as a printer) in the firmware, rather than as software that is loaded on a network server.
The advantage of an embedded Web server is that it provides an interface to the product that anyone who has a network-connected computer and a standard Web browser can open and use. No special software needs to be installed or configured.
With the HP Embedded Web Server (HP EWS), you can view product status information, change settings, and manage the product at your computer.
NOTE: In this guide, the terms “product” and “device” are used interchangeably. When products or devices are discussed in this guide, the information pertains to HP LaserJet printers or multifunction peripherals (MFPs), or HP Digital Senders. For specific information about the features that your printer, MFP, or digital sender supports, see the documentation that came with your product.
Features
You can use the HP EWS to view product and network status and to manage printing functions from your computer, rather than at the product control panel. With the HP EWS, you can perform these tasks:
- Upload firmware updates.
- View control-panel messages and product-status information.
- Determine the remaining life for all supplies and configure specific ordering information for supplies.
- Gain access to the product’s technical support page.
- Gain access to specific support for recent product events.
- Add up to five additional links or customize links to other Web sites (if a permanent storage device is available).
- View and change product configuration, such as tray configurations.
- View and change network configuration.
- View and print information pages, such as the Configuration page.
ENWW What is an embedded Web server? 1
- Receive alerts about product events, such as when the product is low on supplies, through e-mail. Set up four different destination lists for each user (administrators and service), with up to 20 recipients on each of the four lists (if a permanent storage device is available).
- Select the language in which to display the HP EWS screens.
- Print to an HP product without having to install the product print driver.
- Conserve energy by scheduling the product sleep delay so that the product will go into sleep mode after a period of time of not being used.
- Schedule wakeup times for each day so that the product has finished initializing and calibrating by the time it is to be used.
- Send product configuration and supplies usage information periodically to your service provider.
- Configure security settings for the product.
HP Web Jetadmin and the HP Embedded Web Server
HP Web Jetadmin is a Web-based system management tool that you can use with a Web browser. The HP EWS and HP Web Jetadmin work together to meet all of your product-management needs. You can use the software to install and manage networked products effectively. Network administrators can manage networked products remotely, from practically anywhere.
The HP EWS provides a simple, easy-to- use solution for one-to-one product management in environments that have a limited number of products. However, in environments that have several products, you might want to use HP Web Jetadmin to manage groups of products. With HP Web Jetadmin you can discover, manage, and configure multiple products simultaneously.
HP Web Jetadmin is available from HP online support (HP Web Jetadmin www.hp.com/go/ webjetadmin).
System requirements
In order to use the HP EWS, you must have the following components:
- A supported Web browser. Browsers that support embedded Web servers include (but are not limited to) the following:
- Konqueror 3.5 or later
- Microsoft Internet Explorer 6.0 or later
- Mozilla Firefox 1.0 or later
- Opera 9.0 or later
- Safari 1.0 or later
- A transmission control protocol/Internet protocol-based (TCP/IP-based) network connection.
- An HP Jetdirect print server (embedded or enhanced input/output [EIO]) installed in the product.
Opening the HP Embedded Web Server
Use the following procedure to open the HP EWS.
2 Chapter 1 Overview ENWW
NOTE: You cannot view the HP EWS screens from outside of a firewall.
- Open a supported Web browser.
- In the Address or Go to field, type the IPv4 or IPv6 TCP/IP address, the host name, or the configured host name that is assigned to the product. See the following examples.
- IPv4 TCP/IP address: http://192.168.1.1
- IPv6 TCP/IP address: http://[2001:0ba0:0000:0000:0000:0000:0000:1234]
- Host name: npiXXXXXX
If you do not know the TCP/IP address for the product, you can find it by using the control-panel menu or by printing a configuration page. For instructions, see the user guide that came with your product.

Login and logoff
The HP EWS has screens that can be used to view product information and change configuration options. The screens that appear, and the settings on them, vary according to how you gain access to the HP EWS: as a general user, an information technology (IT) administrator, or a service provider. These passwords can be customized by an IT administrator or a service provider.
In a password-protected HP EWS, only the Information tab is available to users who do not log in by using the password. If no password has been set (which is the default), all of the tabs are visible.
If a password has been set, you must log on as an IT administrator or a service provider to gain access to the protected HP EWS tabs (Settings and Networking).
NOTE: For information about changing passwords as an IT administrator, see Security on page 35. If you are a service provider, see your product service guide.
4 Chapter 1 Overview ENWW

Control Panel Snapshot
The Control Panel Snapshot screen shows the product control-panel display as if you were standing at the product. Because this view shows the product status, it can help you troubleshoot problems with the product.
NOTE: The appearance of the screen might vary, depending on your product.

NOTE: The Print screen (and the Print menu on the left) is available only if it has been configured to appear on the Security screen under the Settings tab. Use the Security screen to disable the Print screen if you do not want it to appear for security reasons. For more information, see Security
Use the Print screen to print print-ready files or to update your product firmware remotely.
You can use the Print screen to print one file at a time from a product that supports the HP EWS. This feature is especially useful if you are a mobile user, because you do not have to install the product’s print driver in order to print; you can print anywhere at any time.
You can print print-ready files, such as documents that have been generated by using a “print to file” driver option. Print-ready files commonly have file name extensions such as .PS (postscript), .PDF (Adobe Portable Document Format), and .PRN (Windows print-ready File).
You can also use the Print screen to update your product firmware. This feature is especially useful because you do not have to install additional software in order to update the product firmware. When updated firmware files are available for your product, you can download them your product support Web site:
www.hp.com/go/ljp4010series_firmware or www.hp.com/go/ljp4510series_firmware
To disable the Print screen, on the Settings tab go to the Security screen and select Configure Security Settings. Select or deselect the desired option.
