How does a wireless photo printer work?

Wireless printers use WiFi signals to communicate with your wireless home network. This lets you print to them from any computer connected to the network.

It also let you roam around your house with a laptop and still be able to print your photos.

Some cameras can communicate to wireless printers directly, so that you don’t need to load the pictures on your computer before you can print them.
