HP Embedded Web Server and HP Toolbox
HP embedded Web server (HP EWS) and HP Toolbox are both tools that can be used to remotely
configure products on a network. Both HP EWS and HP Toolbox are used with a Web browser and
they have a similar look and feel. Many of the pages in HP EWS are nearly identical to HP Toolbox
pages. However, there are several key differences between the two utilities:
■ HP Toolbox is used to manage the products that are installed on the client machine where
HP Toolbox is installed. HP Toolbox gets the address of the printers from the registry entry of the
port that the printer is using.
■ HP Toolbox can also be used to manage locally connected products.
■ To access HP EWS the user just needs to know the transmission control protocol/Internet
protocol (TCP/IP) address of the product. No software needs to be installed on the user's
computer.
■ For most products, HP EWS can be directly accessed only when both product and computer are
equipped with network cards (or some form of network connection). In these cases the Web
browser directly accesses the product's TCP/IP address. The only Web pages available are
those that are served from the product.
■ HP Toolbox supports network and direct connect forms of printer connectivity. The browser
directs itself to a locally hosted TCP/IP service that monitors the printing port (be it network or
direct connect). HP Toolbox Web pages are generated through a combination of locally installed
Web content and data that is retrieved from the product. These Web pages also facilitate product
control. On some products, HP Toolbox provides a link to the printer's HP EWS page, but these
are not accessed directly through the browser, but rather through the locally hosted TCP/IP
service.
■ Toolbox provides the Select Device page, which is used to choose which of the locally installed
devices to manage (if more than one has been installed).
The HP EWS and HP Toolbox utilities are described in detail in the following sections.
HP Embedded Web Server
The HP EWS is a standard feature for the HP LaserJet 2420d, 2420n, 2420dn, 2430t, 2430tn, and
2430dtn printers. It is not supported for HP LaserJet 2410 and 2420 printers.
The HP EWS provides a simple, easy-to-use solution for one-to-one product management. In offices
that have a limited number of products, remote management of printing devices can be
accomplished without installing any management software, such as HP Web Jetadmin. The only
requirement is that the management console have a supported Web browser.
In environments with a larger number of products, where one-to-one management is impractical, the
HP EWS and HP Web Jetadmin work together to provide scalable remote product management. Use
HP Web Jetadmin for consolidated management tasks, when you want to perform operations on a
selected set of products instead of on individual products. For such environments, HP provides
hooks between the HP EWS and HP Web Jetadmin so that you can configure HP EWS features on
multiple products in one operation. For example, you can set the security password for the HP EWS
simultaneously on a cluster of products.
