The parallel port connector connects to a printer. The NANO-LX comes with a multi-mode
(ECP/EPP/SPP) parallel port. The CN20 parallel port interface features a 26-pin flat-cable
connector that requires an adapter cable if a traditional DB-25 connector is preferred. The
parallel interface can be re-assigned to LPT2 or LPT3 through the BIOS configuration
utility. The default interrupt channel is IRQ7. Select ECP or EPP DMA mode using the
BIOS configuration utility.
