Updated: 04/26/2017 by Computer Hope
Short for extended capabilities port, ECP was developed by Microsoft and Hewlett-Packard and announced in 1992 as an additional enhanced parallel port. Although ECP requires an additional DMA (direct memory access) channel that may cause resource conflicts, it can transmit up to 2 MBps and has a FIFO (first in, first out) buffer of up to 16-bytes.
