Detailed explanation-1: -EPP/ECP (Enhanced Parallel Port/Enhanced Capability Port) is a standard signaling method for bi-directional parallel communication between a computer and peripheral devices that offers the potential for much higher rates of data transfer than the original parallel signaling methods.
Detailed explanation-2: -As we’ll see further below, there are three different type of LPT ports, SPP, EPP and ECP, each supporting different speeds and features, but all use the same direct cable connection. A standard LPT port will provide speeds of 40Kb/s to 60Kb/s while the faster ECP ports will deliver up to 1.1 Mb/sec or 8.8 Mbps.
Detailed explanation-3: -A parallel port is a type of interface found on computers (personal and otherwise) for connecting various peripherals. The IEEE-1284 standard defines the bidirectional version of the parallel port. In its standard form, it allows only for simple communications from the PC outwards.
