2.11 Printer port Connector (CN4)
Normally, the printer port is used to connect the card to a printer. The
PCA-6780 includes a multi-mode (SPP/EPP/ECP) printer port accessed
via CN4 and a 26-pin flat-cable connector. You will need an adapter cable
if you use a traditional DB-25 connector. The adapter cable has a 26-pin
connector on one end, and a DB-25 connector on the other.
The printer port is designated as LPT1, and can be disabled or changed to
LPT2 or LPT3 in the system BIOS setup.
The printer port interrupt channel is designated to be IRQ7.
You can select ECP/EPP DMA channel via BIOS setup.

The PCA-6780 provides a 50-pin socket for CompactFlash card type I/II.
2.12.1 CompactFlash (CN22)
The CompactFlash card occupies a secondary IDE channel which can be
enabled/disabled via the BIOS settings.
