Using the Embedded Web Server

  • PrintPrint

Introduction

Use the Deskjet printer embedded Web server (EWS) to do the following:
  • Adjusting network configuration
  • Configuring network security
  • Restricting access to Configuration pages
  • Checking printer status and estimated ink levels
  • Viewing network statistics
  • Linking to HP's Web site for support
  • Ordering supplies

Preparing to open the EWS

Do the following two items before opening the EWS:
  • Make sure that the printer and the computer are powered on and connected to the network. To access HP support through the EWS, the computer must be connected to the Internet.
  • Print a Network Configuration page. Note the IP address and the URL of the printer. To print a Network Configuration page, press the Network button while the printer is turned on and idle.
If the printer has just been connected to a network, it may take a few minutes for the printer to determine its network settings. Wait a few minutes before printing the Network Configuration page in order for the network settings data to be valid.

Opening the EWS

Follow these steps to open the printer's EWS:
  1. Open an Internet browser. Use Internet Explorer 5.0 and higher or Netscape 4.75 and higher.
  2. Enter the URL of the printer in the address box, and then press Enter.

Using the EWS

The HP Deskjet 6840 EWS has three main tabs (Figure 1).
  • Home
  • Settings
  • Networking

Connections Enabled Hardware address Connected IP addressSubnet mask
Wired (802.3)Yes 00-0e-7f-ce-38-54No
Wireless (802.11) Yes 00-0e-7f-ce-38-55 Yes 169.254.56.85 255.255.0.0
The Connections table shows the printer's MAC and IP address, and subnet mask. 802.3 and 802.11 cannot run simultaneously. If one is enabled, the other is automatically disabled. USB can run simultaneously with either 802.3 or 802.11.

Settings tab

Select language

Use Select Language to change the default language used by the HP Deskjet EWS. By default, the HP Deskjet printer Web page uses the same language as the Internet browser used. In order to support manual language selection, the browser must be enabled to accept cookies (see the browser's documentation to enable cookies). The language choice will remain in effect until the browser is closed or the browser's cookies are deleted. Changing the language setting for the printer's EWS does not affect the browser's language setting. Follow these steps to select a language for the printer's EWS:
  1. Select a language from the drop-down menu.
  2. Click Apply.

Refresh rate

Configurable setting determines how often EWS information is updated in seconds.

Networking tab

General

Device
Host Name"Friendly" name that identifies the printer on the network.

  • Up to 15 ASCII characters.
  • Must be unique on the network.


Windows users can access the EWS with the Host Name. For example, if the Host Name is kids-printer, access the EWS with http://kids-printer. This technique applies only if you are on the same subnet.

Connections

Wired
IP Address configuration
Automatic IPIf the printer finds a DHCP server on your network, it requests an IP address from it. Otherwise, the printer creates a valid, unique IP address using the Auto IP standard.
Manual IPIP Address, subnet mask, and (optionally) default gateway are manually assigned and entered.
Manual IP AddressEnter the IP address. Each value must be valid, and in the form n.n.n.n, where each n is a number from 0 to 255.

Network connectivity with the printer will be lost after assigning a manual IP address. Use the new IP address to reconnect to the printer.

If unable to reconnect to the printer, refer to the printer's documentation to reset the printer to its factory defaults.
Manual Subnet MaskEnter the subnet mask. The mask determines which bits specify the network, subnet, and printer.
Manual Default Gateway Enter the IP address of a router or computer that connects to other networks or subnets. If none exists, use the IP address of your computer or printer.
DNS Address Configuration
The Domain Name Server translates IP domain names or IP device names into IP addresses.
Automatic DNS ServerThe DNS Server value is supplied by the DHCP server.
Manual DNS ServerEnter the IP address of the (DNS) server. If the DNS server is located on a local network, obtain the address and provide it.

If the DNS server resides with the Internet service provider (ISP), obtain the address from the ISP.
Manual Preferred DNS Server This DNS value is used first.
Manual Alternate DNS Server This DNS value is used second.
Advanced
Network Interface
  • Enable: Enables the network interface.
  • Disable: Disables the network interface.
Speed and DuplexAuto Negotiation: Speed and Duplex negotiations are automatically performed.

Manual Negotiation:

  • Manual Speed: Select 10 Mbps or 100 Mbps.
  • Manual Duplex: Select Full or Half Duplex.

Network settings
InfrastructureWireless devices communicate with each other through a wireless access point (WAP), such as a wireless hub, router or gateway.
No Authentication or EncryptionSelect if you do not want to use security settings.
WEP (Wired Equivalent Privacy) encryption helps protect network traffic. WEP requires the specification of Key.

  • Key: Enter the WEP Key. All devices on your network must have the same WEP key. A WEP Key can contain up to 5 ASCII characters or 10 Hexadecimal characters for 40-bit encryption, or 13 ASCII characters or 26 Hexadecimal characters for 128-bit encryption.
  • Confirm Key: Re-enter the WEP Key.
  • Index: When using WEP encryption, the sender and the receiver must agree on both the WEP Key and index. The index is a number between 1 and 4.
WPA-PSK
  • Encryption:
    • TKIP scrambles the keys and ensures that the keys have not been tampered with.
    • AES Advanced Encryption Standard, for printers that support AES, is a symmetric 128-bit block data encryption technique that works at multiple network layers simultaneously.
  • Pass phrase: Enter a pass phrase. (8-64 ASCII characters)
  • Confirm Pass phrase: Enter the pass phrase again
Ad Hoc Wireless devices communicate with each other directly, without going through a WAP.
Channel (Ad Hoc only) The printer uses this channel to broadcast its availability if it fails to connect to the specified network.
No authentication or encryptionSee above
WEP See above
Compatibility
In an infrastructure network use 802.11 behavior.
In an ad hoc network use 802.11 behavior.
