User Manual
Before you begin, check your equipment:
● The printer should be set up and on.
● The Ethernet switch or router should be on and functioning correctly.
● The printer and the computer should be connected to the network (see Connect the printer to your network
on page 13). The printer can be connected by Ethernet or Wi-Fi.
Now you can proceed to install the printer software and connect to your printer.
Printer software installation
1. Make a note of the printer's IP address from the front panel (see Access the Embedded Web Server
on page 23).
2. Install the product software from http://www.hp.com/go/T120-T520/drivers. Follow the software
installation instructions on your screen.
3. The system automatically detects whether you are using Windows or Mac OS X, and you can then choose
which specic software you want to install (by default, all of it). If your computer fails to nd any printers on
the network, the Printer Not Found window is displayed, which helps you to try to nd your printer. If you
have a rewall in operation, you may have to disable it temporarily in order to nd the printer. You also
have the options of searching for the printer by its hostname, IP address, or MAC address.
In some cases, when the printer is not in the same sub-net as the computer, specifying the printer's IP
address may be the only successful option.
Connect a computer to the printer by USB cable (Windows)
You can connect your printer directly to a computer without going through a network, by using the printer's built-
in Hi-Speed USB device port. A USB connection may be faster than a network connection, but it has some
disadvantages that you should bear in mind:
● The cable is of limited length.
● It is more diicult to share the printer.
● You cannot use Web Services.
● You cannot use automatic rmware updates.
NOTE: The use of non-certied USB cables can lead to connectivity problems. Only cables certied by the USB
Implementor's Forum (http://www.usb.org/) should be used with this printer.
Printer software installation
The following instructions apply if you intend to print from software applications using a printer driver. See
Printing on page 38 for alternative ways of printing.
1. Do not connect the computer to the printer yet. You must rst install the printer software on the computer,
as follows.
2. Install the product software from http://www.hp.com/go/T120-T520/drivers. Follow the software
installation instructions on your screen.
3. In some cases, you may see a message warning you that the installer would need to communicate through
the rewall in order to search the network for printers. As you have no need to do this, you can check the
box Continue installation without searching the network.
4. If you see a list of networked printers, click Help me nd my printer (including network and USB connected
printers).
