Parallel Port

Parallel port supports standard parallel, Bi-directional, ECP and EPP protocols. The Super I/O (W83627HG) chip provides the parallel port interface signals.

•The Parallel interface shares signal lines with the Floppy interface. The BIOS settings determine which one is operational.

•Supports Standard Printer Port (SPP), Enhanced Parallel Port (EPP) and Enhanced Capabilities Port (ECP)

AStandard Parallel port cable pin-out is listed in Table 3-17 for reference along with the J3 connector pins. A DB25 connector can be located on the custom baseboard if desired.
