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.
