| 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 |
