Description
The normal parallel port mode is used. This is the
default setting.
The parallel port can be used with devices that
adhere to the Enhanced Parallel Port (EPP) specifi-
cation. EPP uses the exiting parallel port signals to
provide asymmetric bidirectional data transfer
driven by the host device.
The parallel port can be used with devices that
adhere to the Extended Capabilities Port (ECP)
specification. ECP uses the DMA protocol to
achieve transfer rates of approximately 2.5 Mbs.
ECP provides symmetric bidirectional communla-
tions.
