Greetings: There is so much good stuff on RF Cafe that there is no way to list or link to
all of it here. Please use the Search box or the Site Map
to find what you want - there is a good chance I have it here. Thanks!
Parallel Port Pin-Out
EPP was created in 1991 to permit up to 2 Mbps data transfer, and was intended primarily for non-printers.
ECP was created in 1992 to permit higher speed printer communications.
IEEE1284 was created in 1994 to combine EEP and ECP, and relies on the host to determine which standard to use.
