Use the HP Embedded Web Server
This product is equipped with an embedded Web server (EWS), which provides access to information
about product and network activities. A Web server provides an environment in which Web programs
may run, much in the same way that an operating system, such as Windows, provides an environment
for programs to run on a computer. The output from these programs can then be displayed by a Web
browser.
An “embedded” Web server resides on a hardware device (such as an HP printer) or in firmware,
rather than as software that is loaded on a network server.
The advantage of an EWS is that it provides an interface to the product that anyone with a network-
connected product and computer can use. There is no special software to install or configure, but you
must have a supported Web browser on the computer. To gain access to the EWS, type the IP address
for the product in the address line of the browser.
NOTE: For Macintosh operating systems, you can use the HP EWS over a USB connection after
installing the Macintosh software included with the product.
About cookies
The HP EWS places very small text files (cookies) on your hard drive when you are browsing. These
files let the HP EWS recognize your computer the next time you visit. For example, if you have
configured the HP EWS language, a cookie helps remember which language you have selected so that
the next time you access the HP EWS, the pages are displayed in that language. Though some cookies
are cleared at the end of each session (such as the cookie that stores the selected language), others
(such as the cookie that stores customer-specific preferences) are stored on the computer until you clear
them manually.
IMPORTANT: The cookies that the HP EWS stores on your computer are only used for saving
settings on your computer or for sharing information between the printer and the computer. These
cookies are not sent to any HP Websites.
You can configure your browser to accept all cookies, or you can configure it to alert you every time a
cookie is offered, which allows you to decide which cookies to accept or refuse. You can also use your
browser to remove unwanted cookies.
Depending on your printer, if you disable cookies, you also disable one or more of the following
features:
● Starting where you left the application (especially useful when using setup wizards).
● Remembering the HP EWS browser language setting.
● Personalizing the HP EWS Home page.
For information about how to change your privacy and cookie settings and how to view or delete
cookies, see the documentation available with your Web browser.
