In the BIOS setup of my TX motherboard I have three (3) printer port options. Can someone please explain the differences between "ECP", "EPP", "SPP" port settings. I do know that using "ECP" causes me printer problems with my Panasonic KX-P2123 printer. Thanks in advance George Helm -- Those of you who have "been to the edge" know that it's a life changing experience. Priorities change a lot.
