This parallel port connector conforms to the Institute of
Electrical and Electronics Engineers (IEEE) Standard 1284.
There are three standard modes of operation:
Standard Parallel Port (SSP)
Enhanced Parallel Port (EPP)
Extended Parallel Port (ECP)
Table 3 shows the pin-number assignments for the parallel
port connector. The signal names for all three modes are
shown. SSP and ECP signal names are the same; EPP
signal names that are different are shown in parentheses.
