HP LaserJet M4345 MFP Series Products - HP Embedded Web Server

The HP Embedded Web Server (HP EWS) is a standard feature on all HP LaserJet M4345 MFP models that are connected through a network.
The HP EWS provides a simple, easy-to-use solution for one-to-one device management. Instead of installing management software, such as HP Web Jetadmin, use HP EWS for remote management in offices that have a limited number of devices. The management console must have a supported Web browser.
In environments that have a larger number of devices, in which one-to-one management is impractical, the HP Embedded Web Server and HP Web Jetadmin work together to provide scalable remote device management. Use HP Web Jetadmin to consolidate management tasks and perform operations on a selected set of devices. For such environments, HP provides hooks between the HP EWS and HP Web Jetadmin so that HP EWS features can be configured on multiple devices in one operation. For example, you can set the security password for the HP EWS simultaneously on a cluster of devices.
The HP Embedded Web Server User Guide is available on the printing-system software CD. Or, for additional information and a copy of the HP Embedded Web Server User Guide, go to:
Topics:

Configure Device screen
You can obtain device configuration information through a Web browser by opening the HP EWS screen and changing the basic configuration information on the Settings tab. Security and password controls give management information systems (MIS) managers the level of control that they require within their network environments.
  note:
For more information, see the HP Embedded Web Server User Guide.
  note:
The Paper Handling settings are no longer accessed from the Configure Device menus. To configure Tray Size and Type, select Supplies on the MFP control panel.
Alerts
The device can automatically send e‑mail alerts about printing problems or job status to specified e‑mail addresses. For example, if toner is low, the device can notify the person who is responsible for ordering or changing the print cartridge. If a device failure occurs, the device can send an e‑mail alert directly to the person who is responsible for fixing the problem.
These e‑mail alerts can be configured to be sent to any device that can accept e‑mail, such as digital phones, pagers, and personal digital assistants (PDAs). In large environments, administrators can route e‑mail addresses to list-servers or uniform resource locators (URLs) for expanded notification.
  note:
For more information, see the HP Embedded Web Server User Guide.
Security
The HP EWS screens that appear, and the settings on them, vary according to the specific HP EWS. Three modes of user access are possible:
  • General user
  • IT administrator
  • Service provider
To control access to the HP EWS screens, set a password on the Security page.
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 is set (which is the default configuration), all of the tabs are available.
If a password has been set, log on as an IT administrator or a service provider to gain access to the protected HP EWS tabs (Settings and Networking).
  note:
For more information, see the HP Embedded Web Server User Guide.
Digital Sending tab
Use the screens available on the HP EWS Digital Sending tab to control the digital-sending features of the device.
For more information, see the HP Embedded Web Server User Guide.
Kerberos Authentication
Kerberos is a network authentication protocol designed to provide secure authentication for client/server programs by using the secret keys that are delivered with session tickets.
For more information about Keberos or for information about configuring Keberos for your device, see the HP Embedded Web Server User Guide.
HP Digital Sending Software
The HP Digital Sending Software (HP DSS) is a software program that, in conjunction with firmware, enables HP MFPs to send scanned documents directly to electronic mailboxes (e-mail) or to fax destinations, transforming paper-based information into digital images that can be shared, stored, or edited.
Documents are initially scanned at the MFP, and then are transmitted to a network-connected computer where the HP DSS is installed. This prevents users from having to create an electronic copy of a hard-copy document. The HP DSS can also be configured to require user authentication, ensuring that only authorized persons use the digital-sending feature of the MFP.
For more information about HP DSS, see the HP Digital Sending Software Technical Reference.
Networking tab
The HP EWS Networking tab provides access to HP Jetdirect network configuration parameters and status for the device.
For more information, see the HP Jetdirect Administrator's Guide.
HP EWS login process
An administrative or service maintenance user can use the login process to gain access to sensitive information and carry out privileged tasks. This process provides a separate access level for a service provider and contains different page content for different users.
The HP EWS supports two administrative accounts. The user names for the accounts are fixed (“service” and “admin”), but the passwords are configurable. Depending on the authentication status (either not logged in, or authenticated as a service or admin user), HP EWS provides a customized view of the Web content. In a protected system, users who are not logged in will see a limited view that does not divulge any sensitive information. After a successful login, HP EWS customizes the view based on the authentication.
In order to maintain backwards compatibility with Jetdirect and older versions of HP EWS, in which the user name was not required, any user name other than “service” is considered to be the admin user. Therefore, if no user name (or any word other than “service”) is typed and the password matches the admin password, the user is logged in as “admin”. For the service user, both the user name and password are required.
The HP EWS provides two different ways for the user to perform the login process, depending on the current level of protection:
  • If an admin password has been set, the HP EWS presents a Log In link in the upper-right of all pages on the Information tab (the only tab visible to an unauthenticated user) where the user can log in to the system.
  • If no admin password has been set, any user can open any page and have the rights of an admin user. In this case, only the service user content is protected. If no admin password has been set and you want to log in to the system as a service user, you have two alternatives: set an admin password to make the Log in link visible, or append a special argument (&action=doLogin) onto the URL for the HP EWS.
An HP EWS for which no admin password has been set is an "unprotected system." When an admin password set, the HP EWS is a "protected system", and the login process differs.
Topics:
Protected system
When the user first browses to the HP EWS in a protected system, the page that appears is the Device Status page on the Information tab.
All of the pages on the Information tab show the Log In link in the upper-right corner. When the user clicks that link, an authentication pop-up window appears. To log in as admin, type "admin" as the user name, or type any other user name except "service", and then type the correct password. The page remains the same, except the Log In link changes to a Log Off link and all of the tabs are visible, as shown in the following figure.
To log in as the service user, type "service" as the user name and then type the correct password. If the service password has not been set, use the admin password.
To log out from the system, click the Log Off link and close the browser.
Unprotected system
Browsing to the device TCP/IP address in an unprotected system opens the Device Status page that appears on the Information tab, but all tabs are visible. Access privileges are the same as the for the admin user. All tabs and settings are available for configuration tasks.
To log in as a service user on an unprotected system, add the following special argument to the URL in the Address field:
?nav=DeviceStatus&action=doLogin
Adding this argument to the URL and pressing Enter opens a login pop-up window.
Type "service" in the User name field. Type the correct password in the Password field (if a password has not been set, leave the password blank). When a service user is logged in, a Log Off (service) link appears in the upper-right corner the Device Status page.
Password behavior
No admin password is set when the device is shipped, which means that the system is unprotected. Any HP EWS user automatically has all admin privileges until a password is set. After a password is set, only the admin and service users have access to the Security page that is used to configure the password. The admin password can be cleared (set to an empty string) to remove the protection from the system and return it to the default configuration.
The service password in a protected system functions in a slightly different way:
  • No default service password exists (that is, it is empty).
  • If the service password is empty, you must use the admin password in order to log in.
  • When it is set, the service password cannot be cleared.
Configuring service links
When logged in, the service user can customize two service-specific links within the Other Links box on the HP EWS screens. Configure these links on the Edit Other Links page on the Settings tab. This section only appears when someone is logged in as a service user.
  note:
For more information, see the HP Embedded Web Server User Guide.
Configurable ordering information for consumables
The service user can customize the "Ordering Information" text that appears on the HP EWS Supplies Status page.
In service-user mode, an Ordering Information page appears on the Settings tab. This page is not visible in the general-user or admin-user mode. The service user can use this page to set up the configurable text in the Supplies Status page and to add customized ordering information text for all supplies-related HP EWS alerts. If the configured text contains “http://”, it is considered a Web link. This means that all characters after “http://” and before the next space are automatically transformed into a Web link that only opens in a new browser window when the user clicks it.
