Cable Serial/Parallel 1.8m (DB25-M/M)

EPP (Enhanced Parallel Port) is a signaling method defined in the IEEE 1284 standard for high-speed bidirectional communication between PCs and peripherals. It was specifically designed for data-intensive devices.

Think of it as a wider highway where traffic can flow in both directions at the same time, making the exchange of information much faster than on a narrow one-way street.

Hardware-Driven Handshaking

EPP implements the handshaking protocol in hardware, which significantly reduces the CPU overhead compared to standard software-controlled parallel ports.

Key Advantages

• Higher data throughput than standard modes.
• Maintains backward compatibility with older devices.
• Low latency for peripheral devices.

IEEE 1284 was the performance bridge before USB reached the market.
