The parallel port supports three transfer modes: SPP, EPP and ECP. SPP mode (standard parallel
port) is the mode traditionally used to drive a printer. EPP (Enhanced Parallel Port) and ECP
(Extended Capabilities Port) modes are transfer modes that allow transfer rates of 2 and 2.4
Mbytes/s. These modes will only work in connection with peripheral devices which specifically
support them. Cases where these transfer modes are used are, for example, interface conversions
between Parallel and SCSI or Parallel and IDE. The pinouts are different in all three modes.
