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 (SPP)
Enhanced Parallel Port (EPP)
Extended Capability Port (ECP)
Table 5 shows the pin-number assignments for the parallel port connector. The
signal names for all three modes are shown. SPP and ECP signal names are the
same; EPP signal names that are different are shown in parentheses.
