Embedded Web server
This all-in-one is equipped with an embedded Web server (EWS), which provides access to

web programs may run, much in the same way that an operating system, such as Windows, provides
an environment for programs to run on your computer.  The output from these programs can then be
displayed by a Web browser, such as Microsoft Internet Explorer, Safari, or Netscape Navigator.
