How the JetSend communications technology works
Networked devices
To use the HP JetSend capability between networked devices, print a
configuration page to find your HP JetSend IP address, and give your
address to anyone who wants to send information to your printer via
HP JetSend. (See “Configuration page” on page 152.)
From an HP JetSend sending device, a person only needs to enter
the printer’s IP address and press “send.”
Infrared devices
To use HP JetSend infrared capability, line up the infrared sensors
between the sending and receiving devices, and choose the “send”
option on the sending device.
The devices will automatically negotiate the best possible outcome
because they have HP JetSend in them.
Note HP JetSend software is not available for the Macintosh computer.
