You are looking for a wireless printer that will work with a recently purchased laptop computer. You want to connect the printer as a local device. The printer should be operational within 30 feet of the laptop and should be self-configuring.
What type of device interface should you use?
1. USB
2. IrDA
3. 802.11b
4. >>Bluetooth
Explanation : You should use a Bluetooth interface printer. Bluetooth is a radio communications technology with an effective range of 10 meters, or just over 30 feet. Bluetooth devices are self-configuring. Printers often have multiple interfaces, so a Bluetooth printer might also support other interface options, but you would configure the printer to use the Bluetooth interface.
You should not use Infrared Data Association (IrDA) printer. IrDA is an infrared, line-of-site communication technology that is functionally similar to a serial connection. Range is no more than 10 to 20 feet, and can be less, depending on environmental conditions such as dust and ambient light.
You should not use 802.11b. This is a wireless networking communication technology rather than an interface for connecting peripherals. A printer with an 802.11b interface would be designed for connecting directly to the network as a network printer, not for connecting locally to a computer. The printer would likely also have a local connection option, either parallel or Universal Serial Bus (USB), but these are wired interfaces. Communication range is over 300 feet, typically 500 feet or more.
You should not use a USB interface printer. USB is a wired, not wireless, interface.
