What provides for a cordless connection to a printer?
1. IEEE 1394
2. Parallel
3. >>Infrared - Correct
4. USB
Explanation : Many laptops have infrared (IR) ports to allow you to connect to peripherals without a cable. To use the IR port, you must configure it first. Windows usually treats the IR port as a serial port, but it also assigns it a virtual COM port and LPT port.
You need to know which simulated port Windows has assigned to the IR port to configure printing. You must line up the IR port on the laptop and the printer or other device to establish a connection. IR works by line-of-sight, so the IR ports on the laptop and device must be able to "see" each other.
Universal Serial Bus (USB) has become the most popular way to connect peripherals of many sorts, including printers, to modern Windows PCs. USB is faster than serial and parallel ports. Printers have traditionally used a parallel connection, but they can also use the USB or IEEE 1394 Firewire interfaces to connect to printers if the printers support it. Many printers today have USB and parallel interfaces, but few have Firewire interfaces.
