Welcome to the
HP bt400

The HP bt400 wireless printer adapter uses Bluetooth
wireless technology to allow you to print without using a
cable. In general, Bluetooth wireless technology is a short­range wireless technology that allows connection between
devices without requiring a cable. By using your HP bt400,
you can print from your camera phone, PDA, digital
camera, or computer to selected HP printers and all in ones.

Note Check the documentation for your printer to verify

the devices you can use to print to it.

Tip Check www.hp.com/go/bluetooth for a current list

of supported printers and other valuable information
concerning your Bluetooth adapter.

Bluetooth basics

The following concepts will help you use your HP bt400
with your particular printer.

Generally, the sending device (camera, PDA, computer,
etc.) sends a signal and discovers the nearby Bluetooth
printing devices and displays their Bluetooth device
names. Then, you simply print or send to that printer name.

Tip For most devices, the default settings will allow you to

print without making any changes. However, a Bluetooth
device may be set to be visible or invisible and may have
security settings established. If you have difficulty printing
to your printer, consult Bluetooth access modes on page 5.

Welcome to the HP bt400 3

Bluetooth device name

When a sending device discovers the printer, it displays
the printer's Bluetooth device name. The printer's default
Bluetooth device name can be found and changed in the
printer's Bluetooth control panel menu.

Installation and setup

Follow these instructions to install and set up your
HP bt400. More detailed setup instructions can be found in
the user guide for your printer.

Installing the HP bt400

1. Locate the host USB port on your printer or all-in-one.
It will usually be located in the front and is shaped like
the USB port on your computer. It may be called a
camera or Pictbridge port on your printer.

2. Remove the cap from the HP bt400 and insert it into
the port.

LED behavior

The LED on the HP bt400 tells you what is going on.

● Blinking—This is the default state and means the
device is installed and has power.

● Rapid blinking—A sending device is “Discovering” the
HP bt400.

● On steady—The HP bt400 is receiving data.

Bluetooth access modes

Access modes determine how easily a Bluetooth sending
device can print to a printer. The access modes are
defined by the following settings:

● Accessibility

● Security level

Welcome to the HP bt400 5

Accessibility mode

There are two available Accessibility modes for your
printer. Follow the instructions in your device user guide to
change the Accessibility mode.

● Visible to all (public/shown to all) (default)

When the printer's Accessibility setting is set to “Visible
to all”, any Bluetooth device within range can discover
and use the printer. This is the default setting for your
HP device.

● Not visible (private/hidden)

When the Accessibility setting is set to “Not visible”,
only sending devices that have stored the printer's
Bluetooth device address can discover and use the
printer.

Bluetooth device address

Bluetooth devices have a unique device address that
cannot be changed.

The following are general instructions for finding your
printer or all-in-one's Bluetooth device address. Consult
the documentation for your printer or all-in-one for specific
instructions.

1. Access the control panel menu and select the

Bluetooth option.

2. Select Device address and press OK to display the

Bluetooth adapter device address.

Security level

● Low (default)

6 HP bt400 Bluetooth® Wireless Printer Adapter

When the printer's security level is set to “Low”, the
printer does not require a Passkey code. Any Bluetooth
device may print to it.

● High

When the printer's security level is set to “High”, you
must enter the Passkey code in the sending device in
order to print.

Passkey/PIN code

When the printer's Bluetooth security level is set to High,
the sending device attempting to print is prompted for a
Passkey. The Passkey is a 4-digit code that is set on the
printer. The default Passkey is 0000.

The following are general instructions for finding your
printer or all-in-one's Bluetooth passkey. Consult the
documentation for your printer or all-in-one for specific
instructions.

1. Access the control panel menu and select the
Bluetooth option.

2. Select Passkey and press OK to display the printer's
Passkey.

You can also change the Passkey from this menu.

Troubleshooting 13

No page came out or blank page is ejected

File type is not supported by
the profile or the printer. For
example, some profiles do not
support gif, or you may have
accidentally tried to send an
audio file to your printer.

Verify that you are sending the
correct file type to the printer.

Printer is out of range. Move closer to the printer until

contact is established.

Interference from a microwave
or other device.

Try printing again after the
other device is finished.

Too many active Bluetooth
devices.

Only seven Bluetooth devices
can be active at one time. You
must turn something else off.

File is too large. The file may be too large for

the memory in your device.
Modify the file to reduce its size.

Print quality is poor

Photo was taken in low
resolution.

Change the setting in your
camera to take pictures with
the highest quality.

Note VGA resolution (640 by

480) cameras may not produce
a high-quality photo even at
their highest resolution.

Print cartridge needs replacing. Consult your printer

documentation for information
on checking and replacing print
cartridges.

Regulatory Information

This section contains regulatory information. More
regulatory information can be found before the back cover
of this user guide.

Exposure to Radio Frequency Radiation

The radiated output power of the HP bt400 Bluetooth
wireless radio Class 2 is far below the FCC, Industry
Canada and European Union radio frequency exposure
limits. Nevertheless, the wireless radio shall be used in
such a manner that the potential for human contact during
normal operation is minimized. The internal wireless radio
operates within guidelines found in radio frequency safety
standards and recommendations, which reflect the
consensus of the scientific community.

Technical information 19

The level of emitted energy emitted is far less than the
electromagnetic energy emitted by wireless devices such
as mobile phones. However, the use of wireless radios
may be restricted in some situations or environments, such
as aboard airplanes. If you are unsure of restrictions, you
are encouraged to ask for authorization before turning on
the wireless radio. The FCC, Industry Canada and
European Union have set a general guideline of 20 cm (8
inches) from the body when wireless devices are on.

European Radio Approval Information

The HP bt400 is a low power, wireless communication
devices, operating in the 2.4 GHz band, intended for home
or office use. The power output of this device is well below
the RF exposure limits as set by the European
Commission through the R&TTE directive.

The HP bt400 can be operated in the following European
Union and European Economic Area countries:

Austria, Belgium Cyprus, Czech Republic, Denmark,
Estonia, Finland, France, Germany, Greece, Hungary,
Iceland, Ireland, Italy, Latvia, Liechtenstein, Lithuania,
Luxembourg, Malta, the Netherlands, Norway, Poland,

Notice to users in the European
Economic Area

20 HP bt400 Bluetooth® Wireless Printer Adapter

This product is designed to be connected to the analog
Switched Telecommunication Networks (PSTN) of the
European Economic Area (EEA) countries/regions.

Network compatibility depends on customer selected
settings, which must be reset to use the equipment on a
telephone network in a country/region other than where the
product was purchased. Contact the vendor or Hewlett­Packard Company if additional product support is
necessary.

This equipment has been certified by the manufacturer in
accordance with Directive 1999/5/EC (annex II) for Pan­European single-terminal connection to the public switched
telephone network (PSTN). However, due to differences
between the individual PSTNs provided in different
countries, the approval does not, of itself, give an
unconditional assurance of successful operation on every
PSTN network termination point.

In the event of problems, you should contact your
equipment supplier in the first instance.

This equipment is designed for DTMF tone dialing and
loop disconnect dialing. In the unlikely event of problems
with loop disconnect dialing, it is recommended to use this
equipment only with the DTMF tone dial setting.
