ECP : Computer Hardware Buyers’ Glossary


ECP (Enhanced Capacity Port). A faster bi-directional parallel port. This allows the printer to interrogate the printer. A normal parallel port only allows the computer to send information to the printer, not the reverse, except for few bits of printer status. The bi-di port can also be used by LapLink to tie two computers back to back. An ECP port uses a DMA (Direct Memory Access) channel which allows you to efficiently send information to a printer without pestering the CPU (Central Processing Unit) with an interrupt for every character sent.
