Mobile printers are small, light weight and battery powered, available in a price range of $250 to $350. They are ideal for low volume receipt printing, and extremely useful for active professionals to stay connected. Manufacturers provide wide range of connectivity from Infrared Data Association (IrDA) and USB 2.0 connectivity to optional Bluetooth. Here are indicative sizes of mobile printers:

Largest one: 6.5 x 13.3 x 3.2 inches (HWD)

Smallest one: 2.0 x 11.9 x 4.4 inches. They weigh less than some notebook computers. Most come with unrealistic claims of speed; 9 to 14 ppm for black and 2 to 10 ppm for color.
