In this modern life, it’s nearly impossible to find out someone who doesn’t have any idea about wireless network. Wi-Fi exists everywhere, from your home to your office to a coffee shop, a motel, a library. As a result of the development of technology, most of the latest wireless devices offer you the Wi-Fi Direct service. You can have this service coming along with your AIO, your single-function printer, smart phone, tablet, and laptop. With this feature, you can use a mobile device to connect to your printer and have your documents and photos printed out in just a few seconds. To make it clearer, this means Wi-Fi Direct can connect your mobile device to your wireless printer without any intermediary network.
How does Wi-fi Direct service work?
What you need here is just your mobile phone, your tablet, your laptop, or any other mobile devices, and a Wi-Fi Direct-compatible printer. To emphasize once more time, you have no need to have an Internet connection.
In addition, Wi-Fi Direct services can let the two compatible devices recognize each other when they are nearby, since it has 2 useful components – the Service Discovery and Wi-Fi Direct Device Discovery. For example, you have a document that you need to print, and they are stored on your mobile phone, and you have a printer which offers Wi-Fi Direct service. You can put your phone near your printer. At that time, your mobile will display a list of devices that is compatible to Wi-Fi Direct, including your printer. All you need to do is just to choose your printer, and then the document you need to print. Then you will be presented with some printing options, depending on your two involved devices and how they are configured.
If you have more than one printer, up to the app developers, there will be some features which allows your phone to know more details about the services and features of each printer, so that you can choose the most suitable printer to connect to your mobile phone (or your tablet, laptop – any mobile devices you want)
Wi-Fi Direct & Security
You have no need to worry about security because Wi-Fi Direct uses WPS (Wi-Fi Protected Setup) and WPA2, a set of protocols that help you prevent unwanted connection from unwanted devices. This is a good solution for your information security.
Traditionally, with two WPS buttons, Wi-Fi Protected Setup can be initiated on your printer. One button is on your printer, and the other is on your router. The fact that most wireless printers now are coming with WPS can help you find it’s really easy to install. When installing process is finished and everything is ready, you now press the designed button on your router, and press the other one on your printer (hold it for a while). Then you can start printing. It is simple, effective and secure because a live user need to physically press the right buttons in the right sequence at the right time to connect your printer to your desired device. You must follow the procedure, or else, it won’t work!
We are informed available connections when Wi-Fi Direct devices are near together. There will be a signal or an invitation emitted from these devices to other devices. Up to the device, that can be a list which shows you available devices or that can be an invitation. With the first one, you can choose the desired device and start to connect. With the second one, you just need to accept the invitation. It’s a real convenience because no intermediary network and no extra equipment are required.
