An interface cable is not a standard accessory.

• Some computers have a USB and a parallel port. Please buy the appropriate cable for the interface you are going to use.
  
  
• Most parallel cables support bi-directional communication, but some might have an incompatible pin assignment or may not be IEEE 1284-compliant.
  
  
• It is recommended that you use a Parallel interface cable or USB interface cable that is no longer than 6 feet ( 2 meters ).
  
  
• When you use a USB cable, make sure it is a high-speed twisted cable (12 Mbps or 480 Mbps), and that you connect it to the USB connector of your PC.
  
  
• Please make sure that you use a Hi-Speed USB 2.0 certified cable if your computer uses a Hi-Speed USB 2.0 interface.
  
  
• Do not connect the USB cable to the front of your PC or to the iMac's keyboard.
  The HL-5030 only supports the USB interface.
