the embedded web server if your print server is attached to a supported
MFP (multifunction printer) or All-in-One device.
You use your standard web browser for access to the embedded web
server's functions.
To use the print server's embedded web server, open your browser and
enter the print server's IP address as the URL. (Most browsers will take a
simple IP address; if yours doesn't, put an http:// before the IP address.)
If you don't know your print server's IP address, print a configuration
page -- the IP address will be listed in the TCP/IP section.
The embedded web server's screens should be reasonably self-
explanatory, and a little exploration will probably show you what you
need to know. (For full details on the embedded web server, click here.)
All entries show the current values of the print server's parameters, and
you can change those values by entering new ones (if your network
administrator has allowed full access to them). Note that if you change the
print server's IP address, you will lose the connection to the print server.
You can reconnect by pointing your browser at the new IP address.
Some Useful Techniques
Printing a configuration page
To print a configuration page, press the Test button on the print server.
This will print out the current value of the print server's configuration
parameters on the attached printer.
