Description

 

 

Normal

The normal parallel port mode is used.

 

 

SPP/

The parallel port can be used with devices that adhere to the SPP or Enhanced

 

 

EPP

Parallel Port (EPP) specification. EPP uses the existing parallel port signals to

 

 

 

provide asymmetric bidirectional data transfer driven by the host device.

 

 

ECP

The parallel port can be used with devices that adhere to the Extended Capabilities

 

 

 

Port (ECP) specification. ECP uses the DMA protocol to achieve data transfer rates

 

 

 

up to 2.5 Megabits per second. ECP provides symmetric bidirectional

 

 

 

communication.

 

EPP Version

 

 

 

This option specifies the Enhanced Parallel Port specification version number

 

 

 

that is used if the Parallel Port Mode option is set to EPP. This option can

 

 

 

only be selected if the Parallel Port Mode option is set to EPP

 

 

 

The settings are 1.7 or 1.9. There are no Optimal and Fail-Safe default

 

 

 

settings because the default setting for the Parallel Port Mode option is not

 

 

 

EPP.

Parallel Port DMA Channel This option is only available if the setting for the Parallel Port Mode option is ECP. This option sets the DMA channel used by the parallel port. The settings are (DMA Channel) 0, 1 or 3. The Optimal and Fail-Safe default settings are 3.
