extended capabilities port การใช้

• There are many types of parallel ports, but the term has become most closely associated with the "'printer port "'or Extended Capability Port ( ECP ) bi-directional versions.
• This proved adaptable, and led to the " Enhanced Parallel Port " standard, which worked like Bi-Directional mode but greatly increased the signalling speeds to 2 MByte / s, and later the " Extended Capability Port " version increased this to 2.5 MByte / s.
